Sorry if they have a post covering this but I have a question I need some input on. Might be a dumb question but supposedly on the hatchback sport it comes with a special exhaust set up that gives it a little bit more power than the regular hatch. So the question is if I were to get a new exhaust system such as a Greddy Catback or magna flow catback would I lose any power? Id rather not lose any little bit lol sorry again if this is a dumb question.

 

no question is dumb, one you did not ask was the dumb question. Greddy catback or magna flow catback are all better than the stock system, better exit for exhaust.

 

no question is dumb.
