Mac exhaust
 

is paying the extra bucks worth it for the MAC prochamber as opposed to just their regular h pipe? thanx.

i run an off road H pipe with no cats and i like it, but i have never tried the pro chamber... mustangs unlimited.com has the mac pro chambers (no cats) for $229 and the mac off road h pipe(no cats) for $169 and thats for 96-98 do you have headers?

no i don't have headers and I know how much each pipe costs, just wondering if i should bother paying the difference b/c mac claims that prochamber has better hp... and i read an article that proved that the prochamber gained .2 over the h pipe... just wondering if this was really true...

I HAVE A 03 GT OBVIOUSLY AND I HAVE THE MAC EXHAUST H-PIPE WITH CATS AND THE CAT-BACK SYSTEM. THE SOUND IS AWSOME BETTER THAN FLOWMASTERS AND CHEAPER AS WELL. I CHOSE THE H-PIPE WITH CATS BECAUSE OF THE STRICT EMISSIONS LAWS AROUND HERE BUT I HIGHLY RECCOMEND MAC PRODUCTS YOU WONT REGRET IT!!! :)

cool thanx but we were talking about the prochamber...

You probably won't get much of difference in power, I think I have heard maybe + or - 1 or 2 hp. You are mainly getting a different exhaust tone.

thanx that's what i was thinking- so i went to mustangs umlimited and went with the regular h pipe- now the problem is getting someone to install it...

Don't get someone to install it. Do it yourself. It's really easy. You can find a tech article on Mustangworld. With the money you save on the install, you can get a set of MIL's.

can't install it myself- the regular h pipe requires welding because the crossover comes seperate- it didn't know that it was shipped that way until i got it
