I have a Flowmaster single in and dual out to the rear on my x and it sounds awesome... :ylsuper:

I have a Flowmaster custom job installed. I had 3 1/2 inch pipes custom bent with a single exhaust out the rear. It has a noticable difference in sound and performance. While it was only a small improvement in performance, the bigger pipes really opened up the flow and it's apparent.
