Um, you can retain your existing up-pipes. If they're leaking, you might look for a set of bellowed up-pipes. But they have nothing to do with the post-turbo exhaust, so if they're not leaking, I'd leave well enough alone.

 

I just figured easier breathing= lower egts= longer life for the engine. I guess I can leave up pipes on the back burner and get to them after everything else has been done.... Or after I win the lotto lol
