Single Exhaust, pipe just bought it (right behind the CAT)...
I want to go dual-exhaust... Standard OEM parts call for an H-pipe, but according to Mustang Owners, an X-Pipe is better (a little more HP), but a little pricier...
Is it worth going to an X-Pipe, or will an H-pipe do the same without paying a premium?
Depending on the price, I might just get that fixed, without swapping anything, but since I wanted to go dual this summer, I might do it now...
Any Ideas, opinions, insults?
Thanks in advance...
