Been looking at upgrading my exhaust from standard to an aftermarket model. Spoke to a guy who sells the real things and rip offs from China. Price is about a 1/3 of the real thing and he states that the quality difference is more like 10%. look wise i can see much difference on the outside Has anyone bought some and how did they find them. Hey if i can save a few hundred bucks, why not. But i don't want to waste my money either.
