They are "spendy", but when it comes to top quality exhaust systems, there is absolutely nothing better. Stainless, mandrel bent. It'll outlast your car.
Yes they sound good too, and flow extremely well.
I have their 2.5" dual system on mine, and installed their dual 3" system on my Daughter's T. If I had it to do over again, I'd have the dual 3" on my car also. BAD ASS system! and fits!
