|
02-07 downpipe shown above, 08-09 downpipe may look slightly different |
Perrin's WRX & STi high-flow catted one piece downpipe utilizes 49 state legal catalysts to keep you emissions friendly and improving power at the same time. Perrin utilizes high efficiency metal substrate catalysts for optimal performance. These are legal in 49 states as replacements for a defective, missing, or worn catalyst but are NOT CARB legal. Perrin WRX & STi one piece 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. | | The Perrin WRX & STi downpipes use a 1/2" thick flat flanges to prevent warping, and will bolt to an aftermarket or stock catback exhaust. Perrin's Subaru downpipe catalysts are backed by a limited warranty. |

| NOTE: The 02-07 WRX & STi models and 08-09 models use different downpipes. Please choose the correct pipe for your car as described below. |
