Add to Wishlist


Tomei designed the headers to be the 4-2-1 layout with 42.7mm, 45mm, 60mm sizes to help extract the absolute maximum from your EJ25 turbine with the equal length design. The exhaust pressure is controlled best by this layout and you can see the peak power gains at high RPM.

The lost wax process was used to eliminate cracking from welded weak points and for aiding smooth exhaust gas flow with out any interference.You will have a new higher pitched racing sound from the isometric design. With 2.5mm thick pipes made from SUS304 Stainless Steel.

Great exhaust from the best vendor

*2006 STI* This exhaust really sent the torque through the roof. The boxer rumble is gone, but I think the new roar is better. It came with everything you need for an easy install. The only thing to note is that it did not fit with my Perrin subfram braces. Guess which got replaced. The braces. This exhaust is amazing, and Josh always has the best deals. Thanks again.

tomei quality + Josh @ IIR= A winning combo!

amazing quality product is an under-statement! came with everything for an easy install and gave my car a well needed exhaust upgrade before getting it protuned as well as giving me a slightly different exhaust that everyone in my area has never heard! if you want a great product, from a great guy (josh is the man!); give josh a call and pick up this exhaust manifold from tomei
