FYI the reason for the low price is because of the materials (and workmanship). They used pressbent alumanized steel and a forza muffler. Do not be upset when this exhaust has to be replaced shortly. The stock exhaust is mandrel bent stainless steel with a double wall stainless steel double welded muffler...quality. Also, I would be upset with the weld work on that (mig welding, and a very unskilled hand doing it)...

For a quality stainless exhaust, with tig welding, mandrel bent and quality muffler(s)...expect to pay much more. But it will last a lifetime and have no leak issues. The welds are very important on an exhaust because of the constant heating and cooling phases an exhaust goes through, shoddy mig welding will crack and lead to a ticking sound (exhaust leaks).

This is good quality work:



That's a hand built X-pipe for a true dual exhaust for a twin turbo BMW 335i, here it is on the car:



I believe that I will have this shop do my exhaust this spring after I determine the class I will be autocrossing the xfire in.

EDIT:

I don't mean to bash your exhaust, if you like it that is all that matters. I just wanted to point out the reason for the low price and the potential pitfalls with going with a low cost exhaust.
