Details:

The September 2002 model IMPREZA STI was given a big upgrade & improvement. With the introduction of the twin scroll turbo charger & all stainless steel equal length exhaust manifold. With the high performance potential of the new exhaust manifold it was said that development of an exhaust manifold that could surpass the standard type was impossible.

However we at TOMEI challenged that claim and we persistently tried to make that claim false. With over 10 new samples, we extensively put every single model thru its paces and thoroughly tested them. At last, finally we completed the TOMEI EXPREME exhaust manifold which has surpassed the standard model.

Amazing Response!
Unfortunately the distance of the exhaust manifold from the engine to the turbo charger is far on the IMPREZA due of the nature of the boxer turbo engine layout. Therefore the response is greatly affected if the exhaust pipe diameter is enlarged. So here at TOMEI we tested all various types of exhaust pipe diameter combinations & found the best combination of φ38 (pre gathering section), φ42.7 (post gathering section), φ42.7 (support pipe).

Amazing Power
We didn’t only focus on the pipes diameter but also the design layout for the exhaust manifold. By reducing the sharp curves (at the gathering section) & long straight sections, helps minimize exhaust resistance & to increase the exhaust efficiency at higher RPM ranges.

Lightweight
The whole kit with the support pipe weighs in at the combined total of only 8.5kg!!

Dry Racing Sould
The SUS304 stainless steel brings out the sharp racing sounds.

High Durability
The SUS304 stainless steel is strong, robust and has superb rust resistance.

Equal Length Design
The original STD equal length design was adopted as it was the best for minimizing exhaust interference.

Thermo Bandage Included!
Bonus thermo bandage included in the kit! [ 50mm wide- 15M long].

Dual Support Pipe Included!
The SUS304 stainless steel support pipe [φ42.7] is also included in the kit.

Comaptible with STD ECU & TOMEI ECU
The potential is greatly enhanced even with the use of the STD computer unit. But even more potential is attainable with the use of the TOMEI ECU.
