Perrin Performance Catted J-Pipe 2015-2021 WRX

This is the PERRIN Performance J-Pipe. Conventionally known as the downpipe, the PERRIN Performance J-Pipe provides an unobstructed flow path to allow the exhaust gases to exit freely out of the turbocharger. The design features smooth bends that are combined with a larger piping diameter that is an overall major improvement over the OEM unit to improve both the horsepower and the torque while allowing the turbo to react quicker. 

HIGHLIGHTS:

• 304 stainless steel construction
• 3-inch piping diameter
• Thick .500 CNC cut stainless steel flanges will not warp
• Brushed stainless finish
• Clean and precise welds
• Heat resistant to 1800°F
• Smooth bends
• Allows for an unobstructed flow path for the exhaust gases to escape the turbocharger
• Designed with an extra built-in O2 sensor behind the turbocharger to mount a wideband O2
• Increases both horsepower and torque
• Reduces turbo lag
• Will fit on the OEM cat-back, or aftermarket cat-back exhaust system

NOTE: A proper tune will be required
