Gain more power and response as well as cut significantly more weight with our Resonated 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 prevent the SES or CEL lights from illuminating.
Our resonated cat delete test pipe is simply a quieter version of our standard cat delete pipe.
100% bolt-up replacement for restrictive stock cat assembly. Good for 30 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! Please note that this is a custom item, so it is made to order.
