Headers...
Someone mentioned in the Aftermarket blah blah blah thread that if we want performance parts, we need to start contacting companies.
What company would be worth contacting to conduct testing on the IS350 and IS250 for headers?
Once that is decided, we can bombard them with e-mails and calls.
ORRRRRRR....
We need to group together and do some testing of our own on the only ones I know that are available... the Megan headers. It doesn't seem like Megan has done any testing and even if they did, would you believe their results?
Come on people!

I used to be a big Honda fanatic, and there are some awesome companys that make bangin headers out there. I think if people are really serious than we can contact on of them. They make race headers. Im all for it.

IMO The SMSP header is the best, with price and performance. I currently have the DTR and its an awesome header. But I dont know if any of these companys will even try to make something. Being they need a test car and everything.

Designing headders is no easy task, its not like cutting off the existing tubes off the flange and welding on a bunch of tubes. Theres alot of physics/scavanging of gases/firing order of pistons(?), look i dont know exactly but i know its alot.
Course if you look at top fuel dragsters you have just 8 pipes and thats it, i would love to have 6 tubes sticking out of my hood

But it also wouldn't be much of a challenge to do better than the stock setup. It's just about as high tech as a '32 V-8 Ford. No equal length, not even a proper collector. It could be a lot better, just not legal anywhere in the US.

For those that don't know me I am the guy that did the header group deal for the GS4xx cars. If there is enough demand... 20 + SERIOUS people we could possibly do it for the IS350s.
Does anyone have PICTURES of the stock manifolds? Please post.

Here's how Toyco draws them. There's a lot of room for improvement. There may not be a lot of room to work with in the engine bay though.
