Ok, so i have had 2 other stangs with O/R Xpipes on them, and i recently got one installed on my mach 1 which other than flowmasters is bone stock. The problem is it doesnt sound right to me. Its very very raspy. I know X pipes are raspy normally, but this is way much more than either of the other 2 cars ive had one on. I've had it back to the shop, but the guy swears there are no leaks anywhere. Any suggestions, because as it sounds right now, im thinking about going back to the stock mid-pipe.
Thanks
Thanks
