Ya the exhaust mainfold has a cat built into it (one hole big ass piece). I had my buddy do it for me beacuse a bunch of muffler and performance shops wanted like $400-$500 to do it and they pretty much wanted to drop the motor. He just removed the rear enging mount pulled the alternator and wiggled the dam thing out. I do have a tunner SCT X2, so thats no prob for me, though I do have to take the First O2 Sensor and and place it in the slot of the secound O2 sersor. Cause the programer deletes the secound one. Believe me well worth it, sounds like a well done ninja bike at full throtle.
