SpeedCircuit 3" Cat Delete Test Pipe v2.1 for EVO X (EVO 10) and Ralliart

Gain more power and response as well as cut significantly more weight with our 3" SpeedCircuit cat-delete pipe. This TIG welded polished stainless steel cat-delete pipe also includes an additional O2 bung for a wideband O2 sensor as well as a special O2 bung designed to help prevent the SES or CEL lights from illuminating. 100% bolt-up replacement for restrictive stock cat assembly. Good for 15 ft/lb of torque and 15 HP on a mildly tuned engine. A nice compliment to stock downpipe or aftermarket downpipe and any catback exhaust system. Includes all necessary hardware to bolt up to your Evo. For offroad use only!
