All in all it depends on what you are looking for in terms of sound. Myself I've had a 350z with Resonated pipes that was just loud, then a G coupe with FI high flow cats that were amazing not too loud but on high RPMS you could here that VQ roar with my Q I plan on getting the high flow cats. Highly recomennded if you dont want it too loud!
Man why aren't your vids popping up in my feed more?? Your shit is SO informative. I just traded my Hemi for a G37s that I LOooovVE ,NO regrets at All. I Need all this Knowledge you been droppin!
One of the problems with AWD models is that we don't have many ypipes to choose from. Megans y pipes are one of only a few that are sold that fit the 07-08 xfer case.
Bro if you don't quit throwing s in catalytic converter 😂 love your videos and always appreciate the content so don't think I'm hating or knocking you in any way. Have a great weekend
Great vid. First time watching. HFC is the only way I roll. A.) sounds better B.) when I road race the test pipes won’t work in time attack and street classes as the dB levels are too high C.) for NA, and people who drive their car on a track/autoX HFC will give you more mid-range punch where it matters coming out of corners. Test pipes vs. HFC... 2hp difference.... Whoopie doo.... Product plug: Z1 Motorsports HFC has the o2 bungs that have that Stillen looking mid already in it. 2 years running them, and never once thrown a code. Passed emissions here in TX no problem. HFC all the way.
Its very unfair to say all test pipes have rasp, the rasp is completely dependent on the exhaust you're running. The OEM exhaust will rasp extremely loud with test pipes, if you have a decent catback your car will sound so much better with test pipes than hfcs, it'll perform better too.
on my g37 I run a full invidia setup- gemini catback and their HFCs (plus takeda CAI)... no CEL before or after my uprev tune, which I did a week or 2 after installing the HFC's, didn't need the o2 trickers either.
@@torvarrisevans3961 i never had it dyno'd pre-tune so can't be certain... but if OEM specs are correct (330hp x 0.85 = 280hp) I gained about 60hp from CAI, exhaust, and HFC's... however rumor has it my tuners dyno measures a tad higher than most, so maybe cut 5-10hp off my dyno'd 342 rwhp PS: but I should say that after I got it uprev tuned, that shit made a massive difference... driving home that day on the freeway it felt like a different car

Nice.. I'm waiting for my own to reach this week. I also ordered a Z1 plenum spacer and DC Sports hearers and i bought an Ecutek tune for my 08 G37 coupe
Went with the Z1 hfc, still got the rasp not as much but you still get the same amount of power as test pipes. Is what the tech guy told and showed me on the video 🤙🏽
Ik this is 4 years late but on Z1’s website, it says that the G35 DE high flow cats are for off-road use only, do they just have to say that? Like can I put them on my daily driver g35?
Hi Boost, can you please shed some lights? Here are my mods on my 3.7 Q50 that I have but not bolt on yet; Berk HFC, Invidia Gemini, upgraded fuel pump and injectors, then Ecutek tune on E85. All that combined, is 340-350whp is the right number to do an estimated on? Thanks.
@@BoostInMotion I am RWD. Personally, what do you think of headers? Worth the investment? It's my first time on the platform, I'm just trying to figure out which gives me more gain w/o a supercharger price tag. With RTP, it does yields more power, but it's the gas smell that I do not want.
Stock VQ37 You haven’t done the intake manifold swap from the Z1 and If you’re not installing the headers for really cheap or three in about another 5 to 10 whp
Bro i have a question i installed on my g37 sedan a hfc with everything stock so basically i just wanted to increase the power and sound but it didnt have much difference so later on i removed the hfc and made a custom pipe which I deleted the hfc so in other words (pipe from manifold + ypipe all together in one piece) but again the rasp sound is annoying as hell so what do u think if i install the (hfc + custom y pipe) is it gonna give me a good sound + gains if i tune? Just for the info everything else is stock
Bro i know ur comment is from 4 yrs ago but u NEEEDED to have 2 Vibrant Resonators welded into your custom piping. Wouldve helped with over 75% of the actual rasp or wouldve just about toned it down nicely
You got to check engine light find out if the sensors bad first Or if you have an exhaust leak. If those come out to be clear you can use steel wool with an oxygen sensor spacer until you get tuned
Also have a question I am tuned on ecutek on my q50 3.7 and I keep cracking my exhaust I have the scs custom exhaust from speed cultures and driving it for 3 months I’ll get that tin/rattle in like higher rpm’s so could it be my tune causing it? Or something else cause I have replaced my exhaust system 3 times all the same parts just brand new ones
I got Berks test pipes on my 370z. Defined rasp but I felt throttle response was really improved. I could live with the rasp, I just wish my HKS exhaust had a bit more sound coming from it

This is a really helpful video. I need to replace my cats since they’re rattling and old. Not sure if anyone else has experienced what I’m talking about. Leaning towards kinetix HFC because someone near me is selling them for only $270! Should pair well with my ISR single exit exhaust I picked up for $50 on marketplace.
@@3sevsn well the pipes I got that are early kinetix rattle bad on the heat shields and sound like shit. The new ones might be good but I’m gonna switch to res test pipes
If I decide to get HFC over test pipes Will you get a CEL? Not trying to deal with that I’m just looking to replace my cats on my g37 because they’re starting to rattle
You speaking facts bro. I have a motordyne exhaust and it sounds good with the art pipes but now that it’s cold in upstate ny the sound is kinda getting to me and becoming annoying probably gonna switch them out to berk hfc. Can you verify that in ny you can pass inspection with test pipes as long as your car isn’t throwing a code ?
In New York City we don't have inspectors I look at the catalytic converters all they do is check the visual in the sense of tail lights and turn signals. And that you have no codes
I live in NY too!!! I currently have a sport muffler kit by Infiniti on my 3.7 q50S . I’m thinking about test pipes/ high flow cats and a full muffler delete. I was wondering what are your thoughts and if I should do it. I also want to pass inspection
New York isn't strict on catalytic converter modifications. But I would always recommend high flow cats. Because you'll have a less likely chance of getting any check engine lights. Also muffler delete makes your car sound like a GTR but it comes with a lot of drone
I have to correct you in something.... resonated test pipes. The purpose of a resonator is NOT to eliminate rasp in the exhaust. It’s to reduce the exhaust sound in the car. My ‘16 NISMO 370Z will tell your that. Nobody smart will ever say “I got resonated test pipes to get rid of rasp”. If they do... pimp slap them. Also, the ART pipes are for sound, but mainly for exhaust scavenging.
Somone please help. So any hfc that can fit on to a g37 or 370z can fit a 3.7 q50, correct? Bc product marketing says otherwise, or is this just poor marketing?
Stay away from from all test pipes. They will make your Nissan/Infiniti sound like garbage. Rasp for days. Wether you have stock exhaust w/ tp or aftermarket w/ tp it’s going to sound terrible. And with test pipes your car will smell like 💩. Just idling my car it stunk up like a 20ft radius. If you want more sound just get a cat back or axle back.
I don't know why you be shooting flames unless you have a flame map. And at that point you probably don't even care about your oxygen sensors or catalytic converters.
I was thinking about getting headers and hfcs for my 370. I currently only have z1 cold air and a borla s type catback any recommendations or suggestions for me?
You got experience with berk resonated tp's? I been thinkin about pairing them with my 2.5"-->3" cat back I got on there now, but I'm afraid they're gonna be just as raspy if not more than the kenetix HFC's I got on there now
@@torvarrisevans3961 lol I doubt it. I mean I've never had it dyno'd but I couldn't tell a difference just by feel. I mostly did it for sound, but it ended up being too raspy, I just put my oem cats back on after awhile. Never threw a cel tho.
Idk if you have posted a vid already on this but if you haven’t can you explain the intake manifold in the g37 and upgrading it , is it worth it , and what do you have to buy or stuff I’m new asf but this the only channel I watch relating to vq
I have test pipes on my 350z and my check engine light loves to pop up. The codes say sensor 1 which is before the test pipes, not sensor 2. Will a tune fix this? Thank you!
Would you recommend getting hfc without a tune? Just looking to replace my stock cats, because the honeycomb mesh inside of the stock cats are starting to break apart and cause rattling noise on g37 coupe
A ribbon looking section on your exhaust that allows the exhaust to move along with the engine when rotating, andddd also allows for extremely easy installation lol
good topic keep going. I want to increase the sound of my 14 q50 (it has only infiniti sport axel-back). I'm looking to get ART pipes. but is it safe to run them without tune, I search over the internet I don't find answer, is there any one had experience running TP without tune
No one speaks for the m35 guys😔😂 I have an 08 m35 with DC headers, Megan mid pipe and tips, and once I get off from work I'll be adding some high flow cats in the morning. The car as is without the high flow cats rides like butter and no check engine lights at all, plus it sounds a lot better. Normally people go for the g35 and 37 so you, "I", never see a modified m35. I'm 30 and most people that own a m35 are in their 40's 50's, I love pulling up next to them they see and hear my car then I dip on him😆 Fun car to drive even tho it wasn't meant to be a sporty car like the G series.
I,ll be getting berk hfc for my 05 skyline coupe [g35] .when I had my 1990 r32 skidder here in nz. I had the cats taken out. only cos they was going. plus a new exhaust
My mom has been putting 87 in her 3.5DE on and off for the last 2 years. I told her to stop but what can ya do? Still no engine problems with 160K miles. Nissan motors are amazing.

You got a subscribe because I'm about to either get the g37 or the q50
Thank you glad to be of service
Sooooo is hfc or test pipes better ?
Test pipe for most power
Kinetics hfc are the best. It has a built in O2 sensor adapter. Isr does not.
This is a really helpful video. I need to replace my cats since they’re rattling and old. Not sure if anyone else has experienced what I’m talking about. Leaning towards kinetix HFC because someone near me is selling them for only $270! Should pair well with my ISR single exit exhaust I picked up for $50 on marketplace.
Mine are having the same problem. The light rattle. What did you go with. I need some good ones cause I’m in Cali and need to pass emissions.
any update on how it sounds?
Ok
@@3sevsn well the pipes I got that are early kinetix rattle bad on the heat shields and sound like shit. The new ones might be good but I’m gonna switch to res test pipes
Respect! subbed
If I decide to get HFC over test pipes
Will you get a CEL?
Not trying to deal with that I’m just looking to replace my cats on my g37 because they’re starting to rattle
nope... hfc you should pass basic admission test and no check engine light unless you have an installation error
Boost In Motion ahhh
Thank you
You speaking facts bro. I have a motordyne exhaust and it sounds good with the art pipes but now that it’s cold in upstate ny the sound is kinda getting to me and becoming annoying probably gonna switch them out to berk hfc. Can you verify that in ny you can pass inspection with test pipes as long as your car isn’t throwing a code ?
In New York City we don't have inspectors I look at the catalytic converters all they do is check the visual in the sense of tail lights and turn signals. And that you have no codes
Waiting for mine invidia Gemini exhaust and Berk hfc, thanks for your video
Did you receive them?
I have the same setup on my 08 g37s,🔥🔥👍🏻👍🏻
Jerry Garcia yes
Yegor Shumeyko how's the Berks?
Jerry Garcia so far I returned them! Just installed invidia Gemini, some people complaining that berk hfl last not for so long
I live in NY too!!! I currently have a sport muffler kit by Infiniti on my 3.7 q50S . I’m thinking about test pipes/ high flow cats and a full muffler delete. I was wondering what are your thoughts and if I should do it. I also want to pass inspection
New York isn't strict on catalytic converter modifications.
But I would always recommend high flow cats. Because you'll have a less likely chance of getting any check engine lights.
Also muffler delete makes your car sound like a GTR but it comes with a lot of drone
How much did the muffler kit by infiniti cost you?
I have to correct you in something.... resonated test pipes. The purpose of a resonator is NOT to eliminate rasp in the exhaust. It’s to reduce the exhaust sound in the car. My ‘16 NISMO 370Z will tell your that. Nobody smart will ever say “I got resonated test pipes to get rid of rasp”. If they do... pimp slap them. Also, the ART pipes are for sound, but mainly for exhaust scavenging.
Bruh
Somone please help. So any hfc that can fit on to a g37 or 370z can fit a 3.7 q50, correct? Bc product marketing says otherwise, or is this just poor marketing?
depends on the design bur at the current moment they are interchangable
the only reason i want test pipes is cus i can get more whp,
but will highflow cats give the same amount of drone or rasp the ark pipes will?
Stay away from from all test pipes. They will make your Nissan/Infiniti sound like garbage. Rasp for days. Wether you have stock exhaust w/ tp or aftermarket w/ tp it’s going to sound terrible. And with test pipes your car will smell like 💩. Just idling my car it stunk up like a 20ft radius. If you want more sound just get a cat back or axle back.
So then the long tube header would be some different ?
Hey man if you put that fine steel wool in the O2 sensor and you happen to shoot a flame or two won’t that catch on fire ?
I don't know why you be shooting flames unless you have a flame map. And at that point you probably don't even care about your oxygen sensors or catalytic converters.
Boost In Motion my g35 can shoot flames without a map
Fusion Paintball stock exhaust?
What are the difference between hfc and test pipes
Can i use g37 test pipes on my 2008 g35 sedan?
yes
Just got my z1 HFC, now I’m looking for exhausts I can pair with it. Anybody got any recommendations?
Motordyne , tomei or isr thank me later
I was thinking about getting headers and hfcs for my 370. I currently only have z1 cold air and a borla s type catback any recommendations or suggestions for me?
What do you think I’d the best exhaust set up for a 18 q60 3.0 for sound and power it don’t matter the cost
thank you! (:

Hey was thinking about installing Megan racing high flow cats , are those trash too ? I don’t want anything to crack on me down the line
Berk and z1 test pipes are the way to go but ART pipes are the best lol
I just got an art can't wait to install
Hezha Abdullah you’ll love it
You got experience with berk resonated tp's? I been thinkin about pairing them with my
2.5"-->3" cat back I got on there now, but I'm afraid they're gonna be just as raspy if not more than the kenetix HFC's I got on there now
@@dumpsterjedi9323 hey bro are the kinetix hfc good, and do u get good gains from them
@@torvarrisevans3961 lol I doubt it. I mean I've never had it dyno'd but I couldn't tell a difference just by feel. I mostly did it for sound, but it ended up being too raspy, I just put my oem cats back on after awhile. Never threw a cel tho.
You said you run 87 in your g 👀
If I said that I must have been on crack but no I ran 93 on my G
@@BoostInMotion why it gotta be crack?
@@behindthen0thing😂😂😂😂
Idk if you have posted a vid already on this but if you haven’t can you explain the intake manifold in the g37 and upgrading it , is it worth it , and what do you have to buy or stuff I’m new asf but this the only channel I watch relating to vq
I have test pipes on my 350z and my check engine light loves to pop up. The codes say sensor 1 which is before the test pipes, not sensor 2. Will a tune fix this? Thank you!
Yes
Nice information my guy just 1 question....you think getting hfc and still getting a tune a waste of money?
What about 03 get sedan. I been wanting to do this
can anyone help , what , Bank 2 Too Lean Mean ?
Did u get it fixed
nope
Would you recommend getting hfc without a tune? Just looking to replace my stock cats, because the honeycomb mesh inside of the stock cats are starting to break apart and cause rattling noise on g37 coupe
Yes that's perfectly fine
@@BoostInMotion thanks for the feedback man
im having the same problem now and I have the sedan lol
Same here lol they’re starting to rattle
Dude looks stoned 😆
What do you mean by flex section????
A ribbon looking section on your exhaust that allows the exhaust to move along with the engine when rotating, andddd also allows for extremely easy installation lol
I'm looking into possibly replacing my cats(due to rotten egg smell).
Go with a aftermarket high flow cat hfc for short
@@BoostInMotion will do, thanks man!
What do you think about fast intentions hfc.. what about the difference between resonated n non resonated hfc?
One is resonated
@@behindthen0thing thanks smart ass
I got dem supercalifragilisticexpialidocious converters!
Lmao🤣🤣🤣
Helmholz resonators
Crap! I just purchased the ones u say not to for my 370z has flex pipe
good topic keep going. I want to increase the sound of my 14 q50 (it has only infiniti sport axel-back). I'm looking to get ART pipes. but is it safe to run them without tune, I search over the internet I don't find answer, is there any one had experience running TP without tune
Hussain Al-Mussalam it won't damage your engine I asked this myself on a 350z forum your engine will just run rich or lean
after all that its best to leave the pipes alone lol
No one speaks for the m35 guys😔😂 I have an 08 m35 with DC headers, Megan mid pipe and tips, and once I get off from work I'll be adding some high flow cats in the morning. The car as is without the high flow cats rides like butter and no check engine lights at all, plus it sounds a lot better. Normally people go for the g35 and 37 so you, "I", never see a modified m35. I'm 30 and most people that own a m35 are in their 40's 50's, I love pulling up next to them they see and hear my car then I dip on him😆 Fun car to drive even tho it wasn't meant to be a sporty car like the G series.
Those cars are clean. You right not alot of people modify
I,ll be getting berk hfc for my 05 skyline coupe [g35] .when I had my 1990 r32 skidder here in nz. I had the cats taken out. only cos they was going. plus a new exhaust
Did you just say you put 83 in your G... your engine is going to die soon
Noooo
My mom has been putting 87 in her 3.5DE on and off for the last 2 years. I told her to stop but what can ya do? Still no engine problems with 160K miles. Nissan motors are amazing.
