what is the Major difference between these 2 pipes?? I hear that the Prochamber is "better" ....but why is that???? wouldnt that "CHAMBER" just add more restriction???

Samsstang

The Pro-chamber is like an off-road pipe so it flows better! than the catted version, I have the Mac-Catted H-pipe flows alot better then the stock 4cats and went thru my first emmisions this year with no problems.

Islander03GT

the pro chamber is almost like having another muffler in the middle of the pipe instead of an x or h type connection. i've heard the sound is awesome.

Yeah Sams my middle initial but my friemds call me Will. I have a 99GT 35th anniversay edition with a few bolt -ons! If you want it loud you want the pro-chamber! I have the catted H-pipe (MAC) with the Mac cat-back and it has a reall nice muscle car tone , actually a little to loud for my old ass . I wish I would of gotten the Pro-chamber though! it sounds meaner and flows alot better.

NoKturnaL

U say it sounds meaner?? Have u actually HEARD it ??? in real life??? ....So, do u think I should get the MAC catted Prochamber over the MAC catted H-pipe?????

Ive herd it on several different vehicles! again its loud enough for me. I just dont like that 2000rpm drone hard to have a conversation with someone, you got to crank the radio almost halfway up just to drown everything out! BTW have you considered an X-pipe? combined with Flowmasters they are VERY LOUD! my buddy has them on a 98 Cobra Damn is he loud! WAY louder then mine! just doesnt sound musclecar like

madmatt

Get the prochamber, but without the cats if you can. This thing is amazing, one of the best sounds from a mustang EVER! If you get the off road version, just keep the stock pipe for emissions if you even have it. You lose some torque down low, but you pick up a nice amount up top. I bought it for the sound alone though...
