That sounds amazing! Very similar to many turbocharged V8 race cars.

Its funny to keep reading about people complaining how quite/weak sounding the X///M engine is with the stock exhaust... Little do they realize cause is the factory catalyst. Once removed the true sound of the V8 TT w/ 600+hp comes to life.

I can't wait to put my downpipes on in a few weeks.
