Hey whats up guys.... well I just bought a catback exhaust and it came with a test pipe, I asked why and they said that because I had a DX it would need that in place catylac converter! So what does this mean? I live in Tucson AZ, and I know that we have emissions have does it effect that? Does it have a place for my O2 sensers?

 

you wont pass your emission with a test pipe.....

 

What if I put this muffler tip on? It's supposed to be universal. I would have to go to a place that would work on it and weld it on, but what would I tell them to do? I want to keep my cat converter obviously... so I can pass emissions.... but what size pipping? What does mandrel bent mean? Do I want that?
