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 38mm (pre gathering section), 42.7mm (post gathering section), 42.7mm (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 Sound 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 [ö42.7] is also included in the kit.
