ARK TP1301-0010 3.0" Test Pipe Polished 08+ Subaru WRX / STI Hatchback GRD 2.5L

The ARK test pipe is designed to get the most out of high revving motors. We use 3.0" piping SUS-304 stainless steel. We have dyno proven increases in horsepower and torque from mid-range to redline. Each test pipe includes a bung cap hole for O2 sensors and/or CEL fixers without having to drill into your test pipe. The ARK test pipe is a direct replacement for your OEM secondary catalytic converter. All ARK test pipes will bolt directly to OEM factory exhaust and/or any aftermarket cat-back exhaust with OEM fitment. Recommended for off-road use only.
