Comes complete with 3" all 304 Stainless Steel Frontpipe (EVO8-FP) and Stainless Steel and Titanium Catback Exhaust (EVO8-CBE). It is designed to utilize the factory catalytic converter pipe in the stock position so as to maintain street-legal status and emissions compliance. NOTE: Picture shows catless race pipe (EVO8-RP) which is not included but is sold separately. For additional power, you can purchase a Race Pipe (EVO8-RP) to replace the factory catalytic converter with a straight through 3" ID 304 Stainless Steel catless pipe (for off road use only).
