I have an 09 jetta 2.5 with a full magnaflow catback exhaust. I have been looking into headers so I emailed Eurojet about it. I asked if they had any headers for my car, Kenny said, "We are in the process of redeveloping……specs, pricing and photos should be released in the next few weeks". Just wanted to give you guys a heads up.
Also my exhaust is pretty quiet. Only at WOT do people notice that I even have one. Will the headers help it get a little louder? What power gains did you guys see?
