Forced Induction Finished Builds

Down pipes and test pipes are the same thing. All I was recommending was to keep the diameter consistent between the down pipes and car back. If you go with 3" down pipes and a 2.5" catback expect to have to take it somewhere to get the two to mate up.

Ok that clarifies things. Since test pipes replace cats, but I want to keep cats for emission pass, I cannot have downpipes then. or are they called "catted downpipes"?

All you would do is buy HFCs. Make sure they will hold up to the additional heat from the turbos.
