The only video that show both sides, great job guys
Awesome guide. I'll be doing this on the drive at home. This guide shows me it's more than easy to do, but I'll give myself the time it deserves! Thank you for taking the time to make this video.
An excellent detailed video, both for the "home" mechanic as well as mechanics.
Thanks 👍
Thank You for that.
Just subbed I have a 2008 Lexus isf 5.0L v8 finally a channel for mods on a isf thank would like to see more
Thanks for watching and subscribing!
Awesome video well done 👍
Much appreciated! thanks for watching
Dream car 💯💯💯
Marvelous video! Very clear and helpful. And enough to completely throw me off the project. Do you think a regular garage will be able to do this, or should I look for a special skilled place?
Rat Race Maverick it is definitely challenging and a shop that is not used to a tedious install like this could struggle. If you are having trouble finding a shop that has experience doing this install look for one that has done headers on Nissan 350z or 370z. These are not as difficult but have some similarities and if they are quick with that install they can get this one done for sure.
Great video on improving the powerhouse 👍
thanks for watching, hands down the best upgrade available from a dollar spent to hp gained ratio!
Hell yeah
Hire this man at a lexus dealer
Doing this by myself with no lift rn on my 17 RCF 😅🤙🏽
😬 good luck 💪🏻
@@SikkyTV I got it done! Bending the dipstick was the hardest part 🥴😂
Great video! Very informative and well lit up to see whats being described. Are you guys offering sponsorships? My channel is Lexus ISF ( mostly ) related content and this would be a great product to review and show to my Lexus ISF subscribers.
Lam Le Hope they sponsor your F ! got my vote!
Thanks! Glad you like it. We sometimes work with people on this stuff so your best bet would be to send an email to sales@sikky.com and you can make your proposal.
Lam Le is worthy of sponsorship.
Nice setup guys
thanks!
Thank you for this video btw, it was really fun watching it...
Installing these as we speak.
Really surprised by the clearance issues on the passenger side header nuts Especially the top rear ones. Near impossible to get tools on them.
I had the old headers off in 4 hours , that’s with me jacking it up and putting on jack stands in the dirt. Took about 7 hours to put 16 header bolts on to give you and idea of how hard they are.
I had to remove the passenger side starter heat shield and motor mount to get clearance to get a swivel wrench on some of the bolts.
Swivel ratchet wrench is the only tool you can get on half of the bolts. Rest of the install should be easy. Not sure how anybody could install the passenger nuts without taking out the heat shield and motor mount.
Yeah it’s not for the feint of heart! It’s doable but takes some time. The fact that these are massive 1 7/8” tubes makes for a tight fit and limited clearance. Glad you got it done!
Do you sell just the oxygen sensor simulator by themselves?
Thanks for the video guide! You've convinced me NOT to do this myself. I've swapped out the transfer case on an Evo before, and I won't touch this! It reminds me too much of that! And I swore to myself I would never do it again!
+Mack Bolan its good you know when it's too much! Always cheaper to let a pro do it then to attempt and end up having to pay someone to fix it. No shame in that at all!
haha yeah, I've been wrenching on my own vehicles for 25 years. it's more of a time vs money thing. The xfer case came out perfect. I just don't want do something like it again! I'm headed over to Chilly Performance in Tampa to get a quote. If it comes out too high, I might be on my garage floor in 100 degree heat. We'll see.
Also, I give you guys a lot of respect for having the skill to fabricate these headers. It's amazing actually that you can do it and make it all work perfectly from within such a confined space! Some people balk at the price, but come on, it's no easy trick designing these AND have them work, and that's really where all the value is.
Thanks!
+Mack Bolan thanks! It's good to know some people realize the time and effort it takes to R&D a set of headers like this. Have your install guys watch this video. Will save them time and you money.
What a job!
Yeah, it's a bit time consuming lol
@@SikkyTV wat is the micro proses ? You doing it must be done after instal these headers?
Do you sell the O2 harness extension separate?
Can the same steps be used on an 2nd gen IS350?
Cant explain how happy I am to see american companies crafting really nice parts for Japanese cars. Like i always say buy from the home team if possible and keep business local.
Thanks for the support!
Good time to do the starter while you're in there...
Haha yup!
great video with loads of common sense, only question , have there been any issues with the steering shaft going so close to the runners and getting hot enough to cook the needle roller seals and letting water into them ???
jeff8827 no issues with that. Water can't really get into that area either. Between the splash guards under the engine and the location of the steering shaft knuckle it would be surprising if any water could ever get there. Also, the steering shaft isn't any closer than OEM headers.
Yikes, I've done plenty of work on cars but I don't have enough gear for this, I'll have to see if I can use someones hoist ffs, love the isf, hate some of these jobs haha
that definitely doesn't look easy. any recos on shops up in toronto that can handle a quality install? awesome video nevertheless, and keep the ISF content coming!
Yeah, it takes some experience and skill to pull off quickly. Will do! thanks for checking out our video!
wow, that was a hell of an Install.
+phrozen06 ha ha, yeah not for a beginner for sure but hands down easiest of all the header options to install
+phrozen06 it's a big job no doubt
During the video I saw pink Coolant residue on the automatic transmission. Have you checked to see if the intake manifold valley plate is leaking? Common on the ISF. Basically the sealant where the intake manifold meets the heads fails and Coolant leaks past into the valley and then down the back of the engine onto the automatic transmission.
Yeah it appears to be old. Assuming previous owner had some issues repaired and this is the residual
Why the O2 Conditioner that you have its different from PPE Headers? Did the Sikky has their own O2 Conditioner or you bought it in somewhere else? If it's dieffrent, Is O2`Conditioner Sikky are a different from the PPE in installation ( like in cutting wires or its the same way)?
An alignment is mandatory after undoing the subframe....
Don't you have to retorque it after a hear cycle?
damn, use an engine support from up top.
Hey is that your twin 😂😂 or am I just seeing reflections
I have an install for an 07 is350 soon, any major differences that I should know of so I can prep?
Yes, major difference. This is a V8 engine and your car has a V6. Not much similar at all.
Are you planning to make Genesis 5.0 exhaust manifolds?
Not currently in the plans
No any shops in California that can do these..
Do y’all make headers for the GS-F as well?
Yes! See link
www.sikky.com/product-category/exhaust-headers/lexus-headers/gsf-lexus-headers/
Will the sikky headers bolt on directly to the Borla® - S-Type™ Stainless Steel Cat-Back Exhaust System with Split Rear Exit (BOR-12656) ? Please advise. Thanks!
Yes. They will bolt up to factory exhaust or any exhaust designed to work with factory headers.
What about the Cats?
Doe sell these for the is250?
Or do u sell just the micro processor by itself?
We have made them but not up for sale yet. Hopefully some time early this year
Is the collector flange inner diameter the same for the ISF and RCF?
Yes
At Sikky installing this bare without ceramic coat or wrapping, would will the car fair over time, any issues?
under normal circumstances no issues without ceramic coating
so this kit removes the cat completely? I'm looking for headers but the tight emission restrictions in Germany won't work with a decat. any solutions for that?
The ISF has 4 cats, this performance header removes the front header but you still have the secondary cats in place. Cats can also be added back in downstream of this collector to keep things emissions compliant.
Oooof!
Why did you mess with the engine mounts? Were they in the way or do you have to do something to them?
They are in the way when doing the install. There is also this little nub that protrudes from the side of the mount base that does nothing and gets trimmed off. Very very minor modification that does not effect the motor mount in any way.
@ SIKKY rcf and gsf header install soon?
It's basically the exact same install. Really nothing different so this ISF guide could be used for ISF, GSF, and RCF
SIKKY how much are the headers. ??
off topic.... why is there crusty coolant on the bellhousing? leaking somewhere?
dmitry kapralov pretty common with the isf, maybe the water pump was leaking and replaced?
On the rcf is diferent the color from the harndess! How do i install the little black box for not engine light on! You say blank and red and white blanck and red and gray ! Or just i install on the same position! As the isf ? Let me
Know thanks
different wiring for rcf vs isf. Got to sikky.com and check out the rcf product listing. There is a RCF specific wiring diagram on that page
SIKKY perfect i already install a rr tuning and no engine lighs came on! Thanks sikky greay header!
I'm assuming the install for PPE headers on a 2007 IS350 is quite similar?
no, the 6 cylinder engine is much easier.
SIKKY awesome, good to know! Great video btw
I'm usually up for anything as far as AUTO DIY , buuuut idk If this is something I'd tackle myself. Headers are sick as shit though bet they open that beast ALOT. LOL, BUT JESUS THAT'S A HUUGE PROCESS.
yeah it's definitely a process for sure. It takes veteran mechanics about 10 hours. We have done so many now we can do them fairly quick. Is that a Thundercats symbol on your name?
@@SikkyTV damn right🤙😎
rob 49erfan Hell Yeah!!!
Wow great video how much hp will these headers add to the isF
40+ HP to the wheels is the norm. We have seen more in some cases. Granted results will vary based on what dyno you have your testing done on but that's the same for any mod.
Wow what a gain I wanna purchase these for my IsF are u gonna do dyno videos soon ?
Yes, we will be covering that information in the next couple episodes of our project Lexus ISF build.
Yes, dyno videos are coming very soon. There are already several on this channel though so feel free to check them out.
Does that kit come with everything you have done or is it sold separately
The header system comes with everything needed for install. If your talking about the intake then no that is sold separate.
How much for the intake kit n brand
do these headers fit RHD (UK) ISFs????
No. Lhd only
Any plans on making headers for the 06 & 07 GS 430? I'm sure lots of people would appreciate it 🙂
Not currently but if the demand is there we would consider it. We would also need someone with one of these cars local to offer up their car for prototyping purposes.
I hope someone locally can see this message.
SIKKY There's a large following on Club Lexus .
Well ask around and let us know!
Carl Cameron Offer them your car for R&D. It'll be so worth it!!
Is this similar with PPE headers ? Thank you
almost, Engine mounts and mounts brackets have to be removed to get PPE headers into the correct space. If I were you, I would just buy the SIKKY headers. Theyre engineered a lot better. I would also suggest the RR racing tune, its alot easier than ECU manipulation with SIkky.
"You might cuss a few times" 🤣🤣🤣 what are the differences between installing headers on IS-F and the RC-F??? I ask since I notice you commented on someone's comment stating there are some differences.
Question about the install: Why are we removing the rubber donut from the driver side engine mount?
So it doesn't melt from being so close to the headers.
That's what I suspected. Thanks! btw, my installer wants $2000 to install the headers on the RCF! They go by the service manuals when determining hours. They use Alldata to access the service manuals, and the service manual actually quotes 10 hours per side (exhaust manifold replacement). By watching your video, and that you estimate 7-8 hours for an experienced mechanic with a lift and the proper tools, 20 hours sounds really inflated to me. Of course, the service manual instructs you to drain the power steering fluid and disconnect almost everything from the engine due to having to drop the engine down, even if it's only a few inches.
Mack Bolan Not sure if you paid already but $800 should be the max for RCF/GSF header install.
So you will lose the catalytic converters when installing the headers? What about emission test on mot?
The primary cats that are located in the factory header are gone after this upgrade but the secondary cats in the exhaust are still there if not removed also. No issues passing emissions. Hundreds of customers running these for many years with no check engine lights or problems with emissions testing
@@SikkyTV what about California emission inspections? We all know CALI is bad when it comes to changing things like this.
(Not that I'm against it) just sayin
What is the purpose of removing the rubber tops on the engine mount
They get very close to the runners. To avoid melting. Did have a few customers report they left them in and didn't have issues so you could leave if you wanted. personal preference I guess
so its made in the USA...but now aviable in the USA per your website
Are sikky headers as goid as POE in terms of power and strength?
Dyno proven time and time again Sikky headers make more power than PPE. Strength and quality are both good
Why u have to change the oil dipstick and tube? Keep u keep the factory one?
tube clearance
@@SikkyTV but ur tube and the dipstick doesn’t work tho
@@SikkyTV that’s why I’m wondering can I put the factory tube and dipstick back in
why did he remove the rubber off both engine mounts?
That rubber is just a cover and not related to the mount dampening. It's close to the header so it's more of a preventative thing so it won't potentially melt. They could be left on with likely no issues but better safe than sorry.
3:23 dude you just broke the wiring harness clips....very professional
Ha ha, yeah they were super brittle. Can't be perfect all the time lol.
haha, great job man!
How do I get these installed on my ISF if I dont have the jack/tools? Do I order the parts and take it to any mechanic? The installation seems complicated but I assume the mechanic would follow your instructions?
Hey, so yes it's recommended that you use the proper tools and any skilled mechanic can do this installation no problem. You could ask the shop if they have installed headers on any v8's before or even a Nissan 350z. It's not much more difficult than any of these installs.
Can it be installed on Japanese LEXUS ISF？
Only on left hand drive cars
I was expecting a startup and rev at the end
There was one.
thanks for the startup after install puke!
Any time!
Is this same as a is350?
no, is350 is a v6 this is a v8
Does anyone have a install video for installing headers on a 2IS IS350. It's a 2007. Thx.
Not yet but we will when we launch our headers for this vehicle in a couple months so stay tuned!
@@SikkyTV
Headers for the is250's?
Or will these work on a 2006 is250?
Where can I buy it brother?
No longer for sale
This installation work the same for rcf ?
Yes, pretty much exactly the same. A few small differences but the procedure is the same
How long did it take you guys?
We've got it down to a science now having installed so many and can do them much faster than average but as a general rule of thumb the first time through, an experienced mechanic with the proper equipment should be able to do the job in 7-8 hours. The scale goes up from there with less experience and inadequate tools.
nope not a diy...how much u charge for that job?
why take the rubber piece off the engine mount? heat issues? if so.... why not just wrap the headers with ceramic exhaust tape....
So good question. As far as we can tell this piece really seems to serve no purpose. It does not appear to add any vibration dampening since it's not part of the actual motor mount, just sits on top between the mount bracket and the mount bushing but does not isolate either. It's removed because it get's very close to the header runners. It's just something we've always removed. We have had a couple questions about that so we are planning to see if they can be left in on the next in house install we do. It's possible they don't need to be removed at all but either way it does not appear to have any adverse effects on anything. Yes, the headers could be coated or wrapped but it's not necessary if one doesn't choose to do that. Hope that answers your questions for now! Thanks for watching.
Who's the one idiot that gave this video a thumbs down??? Anyhow, won't be doing this mode myself....no more patience these days.
rodk691 😂
The overall cost of this kills the sale for me. Initial cost of headers is one thing, but to pay a shop for 7-8hrs of labor. That's going to be one expensive exhaust mod
Yes, you are correct it's not cheap. But if you look at it from a HP to dollar spent ratio there is no mod that can touch it short of NOS. So it really breaks down to what your goal is with your car. If you don't want more HP and Torque and the focus is more on appearance and handling then yeah it probably does not make sense. If you want to really wake up your ISF and make it feel like a new car with a very noticeable boost in power then it's totally worth it. Look at what people are selling superchargers for. For a fraction of the cost of a supercharger kit you can just about get the same amount of added power. To each his own though, that's the beauty of modifying your car, you can do what you want! Thanks for watching!
This is true! Thanks for the input and a great mod. What kind of hp gains are you expecting from your headers ?
How much do you charge for this install keeping it emissions legal?
that things ugly when you take the covers off
Yeah you can say that again!
Wow.. Never seen under the engine cover of an IS F, seriously ugly haha... Nice vid though!
yeah it really is hideous lol.
Why do you take off the rubber cover for the engine mounts
