02-07 WRX & STI Perrin One-Piece Catted Downpipe
The Perrin 02-07 WRX & STI one-piece catted downpipe features 3" polished stainless steel piping, with a diverted wastegate design for optimal flow. Perrin's wastegate diverter separates exhaust gases behind the turbo and channels them into the exhaust path further downstream to reduce turbulence and improve performance; resulting in smooth, optimized performance. Perrin's 02-07 WRX & STI high-flow catted one piece downpipe utilizes a single 49 state legal catalytic converter to keep you emissions friendly while improving power at the same time.
- Note:
- The high efficiency, metal substrate catalyst is legal in 49 states as replacements for a defective, missing, or worn catalyst but is NOT CARB legal.
- FITMENT:
- Subaru STI 2004-2007
- Subaru WRX 2002-2007
