how much power increase would these headers give a Tundra? Cause I just bought a Tundra a couple months ago.

They make a huge difference on Tundras. Various dynos place them at 15-22 rhwp and some claim even more.

Default JBrady Headers

DaveGS4 and all others:

I met recently with the guy who will be custom designing the header and down pipe for my SC400T project car. Work on this is expected to start within the next 2 weeks. I have sourced an engine as well - 1UZFE to use as the mock guide for my custom header, and exhaust system. This guy is an excellent welder, likes working best with T304 Stainless. If you all are interested, I already asked him if he would be willing to design them, and put them together. His work is first rate, and his prices are reasonable. Let me know.

A point to make- this is not for me to make money, this is to help the Lexus community. I will not need those headers because of my pending turbo project. So, it does not matter to me if you want them or not. This is not for my benefit, but for yours...

Ryan

Ryan, PM me with his contact information and I will call him. I have no problem with someone else doing this project and could even get the stock manifolds sent to him.

wheelz00, congrats on the 14 flat. If you have all the numbers on the timeslip you should post the run and info in the racing forum.

If you have the guys contact information, PM me with it and I will call him.

I have no news from the fabricator to report.

As you can see from my above responses I am open to other options. That said, I also know what it takes to build production headers (or production parts of any kind). It is one thing to build a set of pipes on any given car and quite another to put those into production. You must build the jigs accurately so that each set will be a close enough match to fit when they are shipped to someone.

I have experience with another shop. They do production work and build headers for MANY vehicles. They can custom fabricate and laser cut flanges and components. Now, the all of the same design and fitment problems still exist and the cost from this shop will be higher... around $750... but they will be stainless.

Again, the entire goal of this project was to create manifolding that flowed well (the stock parts do NOT) and that will fit in the stock location and use the stock catalysts (GS400 and 1998-2000 LS400 and SC400).

One off manifolds and relocating the cats would be a different effort.
