Manifolds

Customers have seen up to 15 HP INCREASE when combined with our PnP Subaru Exhaust Manifold. The pipe by itself should net around 5-8 HP INCREASE.
Ceramic Coating to help combat underhood temps, prolong the life of the manifold, and will also keep the exhaust gasses hotter which in turn speeds up velocity.
Boost transition is improved over stock
Helps airflow in the mid to high rpm range
Fits: '02-'05 and '08-'10 WRX, '04-'10 Sti, '04-'09 LGT, '91-'94 Legacy Turbo, '04-'09 Baja Turbo
