You know I value your opinion Jeff and you have a lot of knowledge about everything for this car so I m asking you which would you choose.I don't want to spend 1200 $ for nothing.My buddy Elias who had the Jun full exchast was slower than my car with stock exchast!People say that headers can give you numbers on the dyno but you can't see it on the street!Elias also believes that.
I emailed the guys with the flywheel from Taiwan you send me and they say that they don't have it in stock and that they need an order for 10 pieces to produce it again!
No luck for me in that too

I would avoid headers and maybe just gut the primary cats. The main benefit from headers would be from the scavenging which is not really an issue with boosted cars. Next would be the gain if your manifolds were a restriction. It is my strong opinion that the primary size on the PPE headers for the IS350 is too large which is free flowing but slows the exhaust down too much too early.
Thank you for the reply buddy.My mechanic friend told me the same thing.He told me if i want to get headers i should get the 250 ones.I wonder why Paul from PPE and Mathew from OV told me to use 350headers.I have deleted the secondary cats and i thought it would be best to delete the primary cats
My recommendation is based on how much hp you are going to make. If you are going to be over 300 hp at the crank you should have the 1.75" OD runners which are the IS350 headers. If you are below 250hp then IS250 headers which are 1.63 OD. In between you can choose either one.
Our IS350 headers have been used on a supercharged IS250 before and it did not loose any hp.

Paul

Thank you very much for the reply Paul.Forgive me but if you ask a lot of people opinions you get several answers which don't much all the time and this confuses you to make a decision.Originally Posted by PPEHeaders
