So I plan on changing my stock exhaust soon on my 01 Mustang because who likes to keep that stock? Anyways, I love the sound of the roush Axle back. Would it be possible for me to put roush or the RTR exhaust? I know the pipe midpipe entrance to the muffler is bend on the rtr and roush exhaust. What if I was to cut the bent piece off and weld a straight on it to line up with my midpipe?
