I beleive there is an emissions problem when changing the CAT, is it a problem when only changing the CATback? Ive ben quoted 450 for Difilippo 2.5" Catback system fully installed (1 yr warranty)thanx!vebbers Link to comment https://www.fordxr6turbo.com/forum/topic/47829-exhaust-note/ Share on other sites More sharing options...

I have heard good things about the Difilippo systems, so if the budget can stretch get that in the SS setup Link to comment https://www.fordxr6turbo.com/forum/topic/47829-exhaust-note/#findComment-724633 Share on other sites More sharing options...

You can run into problems when changing the CAT on the BF's as they have a downstream O2 Sensor bit I've heard a few people just get a flash tune and they can get rid of the fault. I have a BFMKII N/A and I just took it to exhaust brothers and for $150 they cut out both the mufflers from the cat back and I got them to put a hotdog in there to act as a resonator and create less drone, so I'm left with a straight through system, and its loud!
