Did some searching but didn't really find the answer that would help me. I have a stock 2006 wrx and just bought a used Cobb catback exhaust and a new Cobb ap v3. On the catback what hardware do I need since it doesn't come with any? I bought a new donut gasket for the stock down pipe, but didn't know if the mid pipe to exhaust tip needed a gasket, so I bought a 3" gasket. Am I on the right track or need more hardware? Then I found out the catback doesn't need a tune, so do I just hold on to the accessport tell I get a aftermarket down pipe? Or can I run stage one? This subaru modding is confusing. If anybody can help I would a appreciate it.
So I got a used Cobb catback with no hardware - what hardware do I need?
And I got a new Cobb v3 with no downpipe - can I run stage one or just buy a downpipe?
