Hey guys let me make a long story short I have become friends with one of the most well respected exhaust fabricators in NASCAR. Outside of being the person that brought the x-pipe,y-pipes, and oval tubing to the race world his setups can be found on 90% of all NASCARS!
So we got to talking and he is willing to make a setup for my 98 gs 400
headers exhaust and also custom mufflers
i think it is worth it and i am going to ship my car out to him so they can do the build
a- would anyone be interested in the same setup for there car
b- He would be willing to give away a few of his custom mufflers and setups for a few people that can help with the project.. as he is looking at going mainstream with his products

hit me up and let me know if your interested

 

a) what setup? as all u have said is he is gonna have headers exhuats (although u meant exhaust headers) and custom mufflers.we need more info... 2", 2.5",3"....catback, axleback, X-pipe,Y-pipe.... etc etc

b) if he does 90% of all nascars setups, i doubt he needs the exposure by giving away a few "free" exhausts to some lexus owners to get his name out.

IBTL....BTW

 

im interested if its free :] wouldnt mind having a better exhaust when the supercharger gets bolted on.

 

Pretty sure Hendrick, Gibbs, Childress, Roush-Fenway and Stewart-Haas and MWR, all do their own exhaust, in-house, so when you say 90%... exactly who are you referring to?

 

sakataj- my thought was to send my car out to him and let him build and do whatever he wants and that would form the base of a unit that could then be remade for others based on him building and fitting it to my car
i will have then answer to you as to what setup he believes would work best for the car (pipe size,x vs y,)
As far as exposure i thought it would be a great idea and i was the one that brought it up to him as to give a few setups away to those in the lexus community that would be able to help with this
i reached out to him about this as i have been on this site for well over 5 years and the fact that there isnt a company that makes a good product when it comes to headers and exhaust/mufflers....

3UZFTE- i have a call with the gentelman in question in 3 hours and will be more then happy to pass along all his racing credentials..

guys all i am trying to do is get the most knowledgeable people and enthusiasts from this forum together with someone that i was lucky enough to have a relationship with to try to get us some much needed quality product and more so some expert input and advice

 

Let us know how it goes. Most exhaust systems are actually worse than stock performance wise, I wonder if he can make one that actually will increase performance? hmmm....

 

i mean im in if its gonna improve performance......just wanted some info.

ok well im in for a free one too....LMK

 

Interested to hear what he says..

Factory exhaust is very restrictive in all aspects, not saying that it is tiny, but it is apparent to those who upgrade their exhaust, that there are gains to be had. I am pretty sure the stock exhaust becomes restrictive around 350rwhp, plus the stock manifolds flows like poop. I'd imagine a nice set of headers and back would increase the exhaust flow a fair amount.

 

Last time i asked a shop to custom make headers for my car....he lol and said, trust me! you rather go turbo. I wounder how much these are gonna cost.

Keep us updated

 

Maybe so, I know Jbrady is the expert about exhaust work for our cars by all the threads and input he's put in. He's been experimenting with different size tubing and y pipes then stock and most them lose power compared to the stock piping circumference while remaining NA. Boosted cars always benefit with larger exhausts and downpipes. So for the 90% of us out there that arent boosted, theres not many gains to be made for our exhaust system. 5whp max

As far as headers go, S&S is about the best short tube design you could get for our cars without relocating the cats and such. Stay tuned because assualt tech is in the works with some 4th Gen S&S headers!

 

Count me in

 

I can agree with you on that because very rarely do we put cams or any real performance NA gains other than cold air. Jbrady is the man and has done all the homework and we'll leave it at that. Looking forward to the new headers.

 

It is always good to get more data about what may or may not make for an improvement for these cars.

I may know who you are talking about although I do not know him in person. I do not know his experience with STREET cars specifically heavy luxury cars with small engines that MUST have low and mid range torque to maintain their driving enjoyment.

Too many people believe that the highest dyno number is the best. This is DEFINITELY not true for cars such as ours. Designing a NASCAR system that is tuned for peak power in the 8000rpm range is hugely different than designing an emissions compliant system that will keep or enhance low and mid RPM power and response while improving peak power.

Actually a system that improves low and mid power WITHOUT increasing peak power would still be a valuable system to use. Conversely a system that picks up 10-20rwhp peak but looses low to mid range power and response would NOT be a valuable system except for someone that is ONLY interested in drag racing and does not care about daily utility and enjoyment for street use.

That said I do not mean to suggest what is being planned is either a good idea or not as I do not know what the plan is. It will be interesting to see what is developed.

 

Interested in seeing what he makes if he does. NASCAR makes specific exhaust systems for when you wing the wee out of your motor, and unless you plan on spinning your car to the moon, might not be the best setup. But it sounds like he would know what he'd be doing, so I guess we'll have to wait and see.

 

ill let him use my car as long as he needs its weekend/show car under construction.
