I used to own an Evo 8 and ran a full catback (greddy) with an N1 tip. Tip was 3 inches, im a fan of the large tip. The dual pipes are nice but not for me. So basically im looking for everyone's advice / recommendations because im a new speed3 owner. I want to increase the airflow / hp. So I was thinking about a catback with a down pipe and a 3" tip. If you could provide pics if you have something similar as well as brands and where to buy that would be a big help!
