How To Gain +50 HP On Your Nissan 370Z or Infiniti G37 With 4 Mods
ฝัง
- เผยแพร่เมื่อ 10 ก.ค. 2018
- After extensively testing hundreds of Zs and Gs with a wide variety of intake and exhaust combinations, I decided to do a test with a customer's 2016 Nismo 370Z. This car was bone stock, and I wanted to see how much power could be gained with the simplest, yet most effective bolt ons I have gathered based on my previous experience.
- Z1 headers & test pipes
- AdminTuning intakes
- GReddy RS dual catback exhaust
Bone stock, the car made 282whp.
Installing headers, test pipes and exhaust (no tune) brought it up to 304whp. (+22whp gain).
Swapping intakes & tuning the car afterwards increased the power up to 326whp. ( +22whp gain).
A total of 44whp gain (50+ crank horsepower) and 19wtq gain with 4 bolt ons, stock throttle bodies, no porting manifolds, no E85. This is a substantial gain while maintaining the complete factory driveability and functionality of the car on 93 octane fuel. - ยานยนต์และพาหนะ
The most non-clickbait video ive watched
Gotta love videos like this.
I see a lot of bs videos on you tube with misleading tittles... honest solid video
Thank you for appreciating this, please share and check out my other videos.
Agreed.
dflet03 -- what are you yappin' about?! Title says +50hp but guy says +44hp. 😂 that's called the typical misleading title you idiot.
+44whp is actually more than 50 crank horsepower, this is shown in the video.
Admin: NICE WORK! You earned my respect again! I think going forward you should have more clear before vs. after videos like this. The camera guy needs a better mic, and the audio from one clip to the next should be level matched, other than that, it's lookin more and more professional with each new video!!!
Thank you so much. I've been looking for an independent take on horse power gains for my 2016. Much appreciated!
this is a awesome style of making the video. enjoyed it! keep it up!
Holyshit! That Z sounds amazing even at idle, reminds me of what my 240Z sounded like
realy good work, i hear ppl saying the Zs were so costly to make small power gains
Them Flames Tho 🔥🔥🔥
Yeah gotta have them lol.
I need this sound in my life.
So 50-55 crank horsepower gain. Not bad for breather mods and a tune. That puts this car right in the ballpark of 390-400hp at the crank from a streetable N/A 3.7 liter V6. That's damn impressive.
a 3.7l v6 vq37vhr is 328-330 stock crank hp and the IPL or Nismo is 348 crank. so approx. 378-388 crank for the regular vhr while the nismo/ipl will easily go over 400 crank
@@vq.krisss i don’t think the horsepower from the IPL is additive. That’s just a better exhaust from stock with a better stock tune, the motor is identical. Mod for mod a g37 sport and a g37 IPL will make exactly the same amount of power.
As far as I understand, the Nismo's only difference is tune and exaust, so I'd say they'll end up around the same all said and done @@vq.krisss
Heavily considering getting a 16 370z when I come home soon. They look fun to drive and I like the design
Awesome video and very informative! I have the same exact car and will definitely be reaching out to you in the near future!
Thanks for the work, another great video
I was gonna do my intake manifold, instead of the headers. Now I got a lot to think about. Great video.
Neither manifold or headers are THAT worth it.. Very marginal gains. Unless 8hp is alot to you
@@R1CEBWL that's about 1/6th of what you can get staying N/A. For what it's worth, it's definitely not allot. Better to save up and go FI.
@@R1CEBWL so the best bang for buck for a stock 370z is test pipes, CBE, tune?
@@r.k862 And CAI 100%
Yea that exhaust was beautiful.
How was i not Subbed to you guys? Anyway, am now. Keep up the awesome work 🤘🤘🤘
Appreciate the good work you're doing for our cars.
Again I really want to do my Tune with you bro, such amazing
44 rwhp is a pretty healthy gain.
My 370Z also started out stock at 282 peak rwhp @ 7200 rpm on q Dynojet, with the low end running moderately lean and the top end running very rich. After putting a Fast Intentions TDX x-pipe exhaust and a Stillen Gen 3 long tube CAI with no tune we got 303 peak rwhp @ 7200 rpm but the F/A ratio was extremely lean at low and mid range with weak torque and the top end was slightly rich. After EcuTek tuning our 7th pull yielded a peak 321 rwhp and a 15 % increase in torque over the entire rev range. The car drives, and sounds, much better than stock.
Moncef is right; these simple breathing mods improve the volumetric efficiency of your engine and when combined with a good tune that is optimized for your engine produce good results at a reasonable price. If I didn't live in California I would have also gone with a good set of equal length long tube headers.
I have similar mods on my G37 but stock headers and yeah the ECUTEK tune took this car from a slug to a missle. Especially the trans (TCM) retuning that is done was unbelievably improved. I feel like the longevity of the vehicle will be improved with all of the corrections to the fuel and trans.
This is the exact mods im playing to get (Fast Intentions X pipe with Stillen Gen 3 CAI). I also live in California so I cant go full route on the exhaust system. Do u mind if i asked u where u got it tuned?
@@mattrancho I had it done at Specialty Z in Simi Valley, a short distance from where Fast Intentions is located. The owner, and tuner, Sebastian Chakoff is top notch and has many years of experience in tuning the VQ37VHR engine. I had 94 octane gas in my tank and had it optimized for the octane; I blend in 1 gallon of Sunoco SS100 race gas, which is street legal in California, with 2 gallons of Shell V Nitro 91 octane to get the 94 octane blend. Sebastian also gave me a 91 octane map that I can toggle to if I need in an emergency. The Z engine runs optimally on 94 octane gas but can safely run on 91, because the ECU retards the timing and richens the fuel ratio if it detects the early signs of detonation.
@@videomaniac108 thank you! Damn sucks i live in NorCal. Most of the good shops are in SoCal. Thanks again bro! Will check them out (still about a year away from buying & tuning my Z)
There's a good shop in San Jose called The Z-Car Garage, owned by Rob Fuller. He has a dynojet chassis dyno and can tune you on either Uprev or Ecutek. He and his people are great; I've dealt with them for a number of things.@@mattrancho
Great vid brother, very helpful 🙏🙏
To the point and no bullshit, very informative with proof
Great video honestly the best one I’ve seen, very helpful.
But the only thing I didn’t get is the intake and tube? It said “Trick Ass Intake and Tune” wtf is that😂
Someone must get a good discount to get all those parts for $2k. I almost spend that on my exhaust ha. Great video, one of the best so far.
Thank you for the feedback. :)
John Powers yeah my stillen was $1500 for my 350
jackalo626 yea my catback was that too, plus if you have test pipes and headers, forget about it
I have a g37 sedan and put 2.5 straight pipe with a x pipe and with the blue chrome tips and cost me under 300$ lol i will never spend so much money on a exhaust
Erik Alvarado it making you happy is all that matters
There is tremendous value in this video and its findings: less than 10 minutes invested watching the video and a ton of information gained.
…Versus the old method of spending 50+ hours in the forums, reading through misinformation and ignorance, with tons of uncontrolled variables.
Thank you for putting all of this together, in the same shop, on the same car, in a single video for all to enjoy. 🍻 ❤️
Thank you very much! We have a couple of other videos like this as well with more modern parts and tuning strategies. I am glad you enjoyed this one and if you have other questions let us know!
Good video & explanations !
This Z transformed into a dragon 🐉
bruh 320whp.... my truck makes more than that stock.
godzilla a natural lol
@@SirBoostAl0t bruh, 326 whp is like 390 bhp, and your truck probably has a v8 with 450 bhp at like 5000 lbs, your truck would get its ass handed to it by this car.
SirBoostAl0t show the dyno link curious to know
SirBoostAl0t boy stfu
So inspiring.
Can’t wait to get a tune by you. I’m working with aam cai, aam test pipes, aam mid pipe and aam short tails. Gonna swap test pipes with art pipes soon then shoot for tune
Awesome video my brother I definitely gained some knowledge!! I'm going to have Jotech do my engine rebuild but that's further down the line so the right bolt on mods for a fraction of the cost is always a plus!!! I know you have both a turbo charged Z and a supercharged one which one do you prefer!?! My options are single turbo or A2A I'm leaning towards A2A even though I want a turbo!!
I was your 3,500th like
This Is legit
🔥
Great video want to see more mods to the Z
You have a new subscriber
Nice vid, How to extract some ponies for your dollar without emptying the bank too much 👍
That last 110MPH backfire~ FAOK!
I really hope that was an afterfire and not a backfire. Backfire is when unspent fuel goes back into the intake, but an afterfire is fuel combustion occurring in the exhaust. Afterfire = probably running a little rich, but flames and pops are cool. Backfire = not the best thing ever because explosions in the intake aren't ideal
Top quality content!
awesome video..i feel confident about same gains for my 1995 Mercedes C36 M104 3.6L inline 6 cyl engine. intake, headers, exhaust, tune.
Greddy Evolution GT! Know your exhaust!
Great gains !! Can u make the 3in intake to work on a m35 with the hr motor ? What you think about the silicone replacement? Thank you for sharing
Cold air intakes are the same for the HR and 370 motors,
Someone needs to get this man lined up
Flames on small tunes jesus im sold
I want a 370z but been going back and forth between that and a 435i… once I got to 4 min I realized why I wanted a Z😫
lmao plz tell me u got the 435 these cars are so slow
When i get my tomei, intakes, and hfc's ill email you for a tune.
cool content.. good methodology
SHOTS FIRED
The VQ god is that you ? Would like to see one of his cars vs Sasha Anis
Can't imagine how quick Sasha's 600hp 350z HR N/A is.. no lag.
93 octane petrol and still runs like a beats.
Now you can imagine what this car will do with 95 or 100 octane :)
And I can buy 101 unleaded Trick fuel right from the pump at a 76 station, just down the road where I live. OH YEAH! Granted a full tank is about $130 in my '11 G37s, but very noticeable power bump!
m.yelp.com/biz/76-gas-station-auburn
It’s still an N/A car. Won’t pick up much. Maybe an extra 10-15 horsepower. But running that kind of fuel, you have to spend loads in fuel lines, bigger fuel pump etc
@@TheNuclearDestress What about with twin trurb? 😈
Йордан Маринов if you twin turbo it and run that kinda fuel yeah you’ll make way more power then normal e85 tune or pump 93
93 AKI (American octane) is about 98 RON.
Well u gave me a good idea on what to buy first
Good honest video fam, keep it up✊🏽✊🏽
Wish I had a good performance shop near me that could do work like this on my g37xs
i really want 400+ hp on the 370z
These upgrades plus turbo that’s what I’m doing to my q40
Ush Yamamoto make videos please I have a Q40!
First two tweaks gained a lot .....nice
I was definitely impressed.
thanks for this video .. ❤
Read through some comments, and I respectfully disagree with people saying it's not worth the money for the gains. IMO, these are solid n/a gains for a decent budget. Perfect for track duty imo, and still fun for the street. And some of these mods would compliment a FI setup nicely, like the exhaust or intake manifold.
Also, it looks like this z would make mid-340's on another dynojet dyno, this one appears to read a bit low. (based on what moncef posted)
The gains are shite, 50 HP and 20 torques for 4000+? Holy shit c'mon dude. It's just sad because that just isn't a good value, it's so much money mate.
@@roboticvenom1935 Unless its a turbo or supercharged engine , what else can get you 50 hp and 20 torque for an N/A engine ?
@@cornholioyo725 easy asf on mustangs and for easily less money, and that's already near 500HP stock, that's a good n/a car
Anyways, it's still not good
@@roboticvenom1935it’s not a mustang
Also, saying its 2k in mods is very misleading. Maybe 2k in parts if thats even possible, it seems more like $2500+ ($1000+ cbe, $300 test pipes, $500 intake, $500 tuner, $200-300 dyno tune), That’s on parts ALONE without labor cost.
I specified in the video that it is around 2k *in parts*.
KingCobra Bolt-ons are DIY. Save the labor costs mane
If you have wrenches, jacks, and jack stands, you can put on all of this yourself. I’m by no means a mechanic and I was able to put on a CBE on my 370 by myself with just those tools. Is it a pain? Yes, but the savings were worth it.
This is basic wrench turning. Do the work yourself and learn a thing or too.
I literally am in the middle of doing a head gasket job on my 2009 G37x. This stuff is easy bolt on stuff. Now if you were having to do what I'm doing at the moment then I would understand because I have done a lot of work on these cars before and know they are a pain in the ass to work on mechanic or not. Still not impossible though. You would have no trouble doing this yourself with even the slightest mechanical inclanation.
That's amazing. I'm still deciding whether to buy a 370z or to go for an 86, but I'm not a fan of the Subaru rumble. Watching this video, would this power increase only work with the specific mods u installed or could I get similar? I'm not very clued up on the technical side of cars but I would definitely like a set up that's similar to yours. What would the parts list be? I like a nice need super sporty sound without the rasp. Amazing video!
My ideal 370Z combo would be:
AdminTuning intakes
Z1 headers and test pipes
GReddy single exhaust (or ISR single exhaust with Y pipe)
Tune
This will make a comfortable 335-340whp in good weather.
Good video, So cats any/all removed(?) Id be curious what the difference would be to make all the other changes, but reuse the current air intake and dropping high flow filters in the boxes. (I'm just not sold on that replacement air filter and they way they lay, and location.
I need this video to blow up
Share it everywhere.
I miss my 2019 heritage addition every day stupid day and stupid reason I lost it I will get another z tho
Wht is the Heritage edition?
Those crackles >>
Great vid
can z1 header possible to install on g37 ?
*I just need enough HP to smoke V8’s* 🤣
I think some of the older stock V8s will be snacks for us. The newers ones like coyote will probably have us for lunch
Ain't gna happen.
Fredo Kush aye bruh you took the words out my mouth forget these mustangs 😂
@@calicammed1le462 with a turbo and a tune ez
Well I mean a 370 z nismo would take out a Mustang got 2011 or older for sure lol but the new ones are to fast
Buddy got his shit shooting flames real quick
Great Video.
I assume a Stillen exhaust system and intake would be good to use?
Can you also recommend the next couple of mods you would do please?
headers + test pipes and a good tune.
Hey guys, just some F.Y.I for you all.
Another issue I had, ( which this time was an easy fix ) ...
Guys when you put in your new Cold air intake kits, The mistake I made was: Did you guys know that your throttle bodies have dedicated hot water lines going into them? Well, I didn't, until by accident I discovered them. You must plug them off or else you are rending your cold air intakes useless, as the hot water lines will " bake" the cold air entering your throttle bodies.
Also do a p.c.v delete, if you don't, because now your Cold Air intakes are allot more intense on air flow, you will actually pull in oil from your valve covers, totally fouling up your throttle bodies, they will be literly caked with black soot.
Anyway, hope all my " mistakes" help you guys!! Have fun, enjoy your 370z!!
PCV is important to clean up the oil from gasses and deposits. If you delete, make sure to add catch cans and change oil more often.
Do a catch can, the hot intake is for cold weather driving. Do not use k&n air filter. Use only paper with added foam. Kn filters will such in sand and debris.
Also needs trans and diff cooler and 2 k oil chnges these cars are a shit show. Just get a brz and add a blower.
Why would I get a BRZ? I would actually get a super charger for my 370z and blow the doors off of Demons Mustangs and Corvettes.
@@mjs1231 did you just say a boxer is less of a shit show than this? Obviously someone is talking out of their ass, because if you want 300whp in the brz you're gonna want to build it. It also cost just about as much as the 370z and the supercharger kits are rather expensive as well. Not to mention boosted boxers are not exactly reliable when modified. Take it from me and thousands of other Subaru owners who have blown an engine because of the detonation and oil pick up/consumption problems.
mjs1231 how should I Mode my 2007 g35 sedan automatic ?
I’m located is washington and I was wondering how much it cost to get the tune by you guys
Mee too haha
Dam that back fire
Good stuff man! U have a video like this for the DE model?
Check out my website www.admintuning.com we have recommended parts for all VQs.
U look like a young tavarish or maybe a thinner tavarish
My car fully bolted and tuned running 94 octane makes as much power as a stock 370Z
Well, damn.
I used to modify Maximas so I feel that pain.
power made doesnt matter as much as how much the car weighs with said power. If you want to make the car faster for free, take some weight out. Superior power to weight ratios win races, not who has the most horsepower.
@@CaptainGameSlayer True. My back seats and cargo liner are deleted, which saves me a few pounds. Car is still heavy af. About 3500lbs
I bought a Z31 turbo, a vg30et that dynoed an embarrassing 150hp/200trq with about 6psi. $1800 (decent condition)
350 hp was made with a couple hundred more bucks, making the cheapest power I can imagine. Looks like there's a few more horsepowers if I do some other simple things, but what can I say, it's my daily! My only issue is the 3000 pounds it weighs!
@@Burden-THE turbo cars typically respond very well to tuning, easy to make big numbers with relatively simple mods. NA cars not so much. What did you have done to your Z31?
I work at nissan. i like the 350-70 platform but they are getting old and lack power now. this vid will help but unfortunately this looks to be a CATLESS install and for most of us not in track use will NOT apply. love the vid tho guys!
I wish all the videos like this one
93 octane??? I use 95 in my lawn mower.
I live in Canada but when I mod my g37xs I want you to tune it, is there a way without me traveling to you?
I can tune you remotely, shoot me an email. Moncef.faik@gmail.com
could you remote tune to New Zealand?
Yes, serious inquiries can email moncef.faik@gmail.com
AdminTuning can you tune a 350z in arizona ?
Yes. Email serious inquiries to moncef.faik@gmail.com.
For $2000 just 44whp that’s insane for what you pay for and what you get compare to a turbo you probably can spend less but will get more out of it. But then then the N/A reliability VQ is way better than turbo cars. I would still pick N/A than a turbo cars. Just less problem in my opinion. The 3.7 is a pretty strong engine. Thanks fo the video.
Dam I'm doing headers exhaust next if I can get those flames. Holy fuck ! That's sweet.
You would have gotten even more power had you used fast intentions long tube headers and exhaust. Mine got me to 315whp without tune.
315whp with that combo is impressive.
AdminTuning mustang dyno if that matters any, I know they read a little different between the brands.
How can u get 315 whp without a tune?? The ecu will compensate and make changes to give factory results
@@georgesmbyd6603 the ECU is going to fight to maintain a healthy timing and it's AFR set point as best as it can. It's not going to magically limit the excess flow. WOT is WOT..
How much HP gain on 91 since California only has 91?
That's cause Cali sucks.
If the guy E85 tune it with these mods i wonder what it will make
15% increase in HP ...NICE!
love you videos man, cant find dual exit greddy anymore online, any advice?
Thats what i did to my g35 and i gain about 40 hp
What did u do
@@VictorLopez-mf7ur did you not watch the video?
Would this setup work for a G37X sedan?
sure
Yo, great Video, how is it handled in America when a cars HP is increased, in Austria (think Germany too) you essential pay insurance for HP (the Brand is also taken into account) but essentially you could have a Ford Focus with 700hp and pay about 600$ a month
So making about the stock whp of a 2004 C5 Corvette 6 speed. Good shit
k&n hot air intakes >
How are those hot air intakes, when they sit right behind the grille and get cold ram air into them?
Nick Motsarsky I was joking about K&N intakes which most definitely sit behind the rad support
Flames....was that after the tune
Yes.
No catalytic Converters or resonator son 🤷🏻♂️
AdminTuning that explains my brothers g37 has test pipes and motordyne ex. Stillen headers and intakes and a tune but doesn’t spit flames Wtf lol I’m buying my brother an Admim tune cuz I want him to be different than the HRs here In SoCal since Saul is famous out here. No disrespect to him but we gonna be different out here in SoCal
some daily 700hp and 900hp cars dont spit flames.. it solely depends on the tune.. whether it has 2 step launch control. antilag or tuned for a brief misfiring to shoot some flames.
Str8Z flames are bad, to much fuel that didn’t burn while tuning. Prolly still messing with injector pulse rate but I doubt any person would leave it that way because it’s sloppy and a waste at best and burnt out cats and a mess of other problems
Man! Awesome!
Wanna try this on my VQ25HR. How do u think, is it possible to gain at least 25 whp on that engine?)
My 01 Maxima needs some Love Monsef^_^
Headers on a HR or VHR is not worth it IMO
This video proves the literal opposite, but thank you.
AdminTuning I mean, I'mnot trying to say anything bad about your work. But from what I've seen, Exhaust and Intakes give around 20whp, and Test Pipes like 10whp. All thats left is only 14, and Tunes usually give around 10 as well.
Exactly, skip the headers and put the money towards FI.
@@admintuning this guy probably can't afford headers, that's why it's not worth it to him
Headers basically get the car ready to get better gains with other mods I'm pretty sure.
I got another one. Want +50hp? Add a spoiler. Want 1320hp? Add a 1320 vid sticker
rohandi antoine thin skinner cant take sarcasm
Fuck off Troll
Wasawat Rojratchadakorn Dodge is doing that lol
So y’all guys install test pipes and headers as well? Also would you recommend getting new 02 sensors before installing the headers and test pipes?
I know it’s been a while since you guys posted this vid. But I have a ‘15 Q50S with the same engine. I just got a couple questions.
1. Any check engine lights after the mods? Not sacrificing daily drivability?
2. If I put these same mods on the Q, and did that small tuning. Nothing crazy, would my trans hold? I’m not chasing power bc I know the car is essentially almost maxed but those are some
Nice power gains out of the same motor
why is the car " maxed" on power ?
No long tubes ? :(
Shorty headers FTW.
honestly? z1 headers are that good?
That doesn’t make any sense
I know it is counterintuitive at first, but the HR and VHR engines make the best peak power and top end power with shorty headers. The merge locations happen to be in just the right place to make good high RPM power with most shorty headers.
Unfortunately, ( ..least for Me ) I got z1 headers for my 2015 Nissan 370z, and they looked like the very same thing as the stock exhaust manifolds, 2015 and newer,Nissan redesigned the exhaust manifolds so that each cylinder has it's own port and tube, changing these out to Z1 headers made absolutely no effect or gain at all, other then a few lbs, and eye candy, that you really can not see unless you are under the car and specifically trying too look.
If you have a 2015 Nissan 370z or newer, Z1 headers make no differences at all. Just a friendly F.Y.I.
Also I changed out my stock intake plenum with a new ported intake plenum from Z1 for $560. plus they demanded my stock one in exchange, and got 0 gain from that as well, How ever, I did get allot more aggressive sound, but that's it, so in total I spent $560. For intake plenum, and headers $ 895 for a total of 1500, plus S&H as well as shop time...... and got 0 gains.
Guy's, really do some checking, asking, and speak to folks that actually know what they are talking about, before you do what I did, and get hosed, please, These companies will gladly accept your money, but when there's " issue" they will tell you : "That's there's no set guarantee and results very" Instantly taking you for your hard earned money, with no power gain detection at all.
I'm Joe Jones, and I'm willing to prove EVERYTHING I just said in this post.
better look a sound than all porsche
Levi Kragt you’re an idiot
Lol okay. You just can’t afford VAG cars. Just stick to the poor mans sports car.
Nadsenec stupid
Would love to see the effect of cams onn top those other mods.
oopppppp vvel
@AdminTuning did you increase the rpm of the car? Looked liked shifts were at 8k great vid btw glad to know you're in my local area always wanted a z
I thought the 370z got 340hp stock?
MIMCK Media that's crank horsepower. Not wheel horsepower.
MIMCK Media no 350bhp/355ps@7400rpm 276ft-lb peak torque.
you´re right . not watched it carefully :)
Actually what really needs to happen: Car HP/TQ should be based on dyno results, but manufacturers want to post the BIGGER numbers because the mouth breathing public has perpetual ADD. Even more helpful would be a simple power-weight-ratio stat for each car. Then all you have left is the driver/gearing/tire choice/surface conditions/temp, but atleast the power to weight / dyno results would make for a more accurate comparison, especially as more vehicles weight approaches that 4000lbs mark.
No
I really hope no one thinks sparks coming out of ur exhaust is a good thing.... flames just mean that ur running rich and don't have all ur catalytic converters (something else everyone seems to think is cool when it just means ur tune is slightly inefficient on the side of safety, running rich is better than running lean). But sparks means u either just blew it engine or are burning away ur catalytic converters.... not good
It's actually not rich at all.
i have a 09 altima thats dumping straight out the cat with litreally nothing else done to it and it shoots flames if im on 93 octane. also if shooting flames was so bad for the car there wouldnt be so many builds out there that shoot massive flames
Sparks are typically just carbon deposits burning off the backsides of exhaust valves. Not a sign of damage.
The car doesn't have any cats
i bet the fuel economy is worse now
Sweet. So theoretically, what other CBE would do even more power and what other things you could possibly do without going into the internals or FI and how much more HP would that give you?
GReddy single would give another 10whp on top of what this one has.
I have a 2016 sport tech with invidia gemini exhaust. I love the exhaust sound of gemini. I wonder if incould pair it with the other mods mentioned with similar results. The exhaust fitted to the car in video had a little more rasp than i like. The gemini sounds exotic. Im also wondering if the Z1 headers are responsible for the rasp
