hey fellers. the placement of the borla in the system makes a big difference in the sound quality. I had mine just before the axle and it was raspy. Now I have it about 6" past the end of the y-pipe flange and it's very deep and less raspy. just thought I would let you know. and my setup is just a XR-1 muffler. Also, the more pipe after the muffler the raspier the sound as well. I have been changing mufflers so much that I made my own custom system where I can change the borla out to the flowtech warlock in my driveway. I'll try to get some pics up this week.

P.S. the borla sounds the best, but the flowtech has the cut-out built into the muffler.
