ok please guys don't give me any crap about oh you get what you pay for this was strictly a test to see were part from ebay were any inferior to buy name brand parts. Now I get that some stuff you really can't skip out on butt in my opinion there are some things that you can be smart about. these mufflers did come from eBay and they were about $50 a piece. they sound magnificent to me. they also are very close to being the same quality if not better than some of the other higher brand out their I was very impressed with the setup and how they sounded. I don't know how much power I gained if any because I haven't had it dynoed and I highly doubt that you would be able to feel a noticeable difference with Just a muffler upgrade. I will be doing a cold air intake real soon and after that getting the uprev tune but for now this is what I have leave a comment and tell me what you think thank you.
