Will any brand downpipes and test pipes work with the perrin catback? I ask this because i want to run catless and perrin only seems to offer catted. Or are diffrent brands ment to fit with same brand exhausts?

 

Thats more like a resonated test pipe than a cat. But back to your question I think just about anything will work as long as they stick to the oem design. That's in reference to where everything bolts up.

 

From what perrin told me there was virtually now difference between running cated or catless for them on stock turbo. There is a member that got a Cobb AP tune with their full TBE and made 341whp on a mustang dyno.

 

just tbe and ap.?no tune, intake,upgraded ic and ic pipes and 341 for real? any dyno sheets?

 

any combination should work fine, since the perrin cbe is built to stock spec, just get UR dp and tp if you want to run a tp or ams or ets etc. . . .
