Cobb Catpipe and Racepipe

A direct bolt in for the Evolution 8 & 9, the Cobb test pipe is a replacement for the factory catalytic converter. Cobb's test pipe will work with the OEM exhaust as well as any exhaust that would keep the factory catalytic converter location. Made of 304 stainless steel with a 3" diameter, the test pipe is available with a high flow catpipe or catless racepipe.
