HAS ANYONE DONE THIS????

[Mach1Run]

Am I missing something? Is it because I ran the exhaust all the way out the back, instead of just dumping it off in the middle of the car?

Cuz this doesn't sound like any garbage trucks I've ever heard...

I think its the cats making the difference.

With the stock H pipe you won't find a better sound then doing this. Even with a catted pipe it dosn't sound bad at all. If you do this with an O/R pipe you better look for something else.

I haven't on a mustang but I did on a 95 Lightning and it sounded pretty good. But I would guess it would sound like some SLP LM1s cause they are nothing but a hollow can.

i orginally ordered a MAC cat back for my 03 GT and when it got to my house, tore off the exhaust from the cat-back. then i opened the package, wrong system... i drove around for about 6 weeks with nothing but the stock h-pipe and it sounded incredible, i was surprised it didn't sound dirty. after fighting with the company for those six weeks i completly canceled my MAC order and got the SLP loudmouth 1 system from a different company. similar sound to the h-pipe only set up but it is much, muuuch louder than the LM1. very happy with the LM1 but i miss my car shaking at a dead idle like it did w/ no muffler
