Mac O/R Prochamber vs. Mac O/R H Pipe

Kevin82693 · September 25th, 2009, 05:49 PM

im looking for a loud deep toned midpipe and ive narrowed it down to this, whats the difference between the o/r prochamber and the o/r h?

SWEET2KSTANG · September 25th, 2009, 06:03 PM

i love my prochamber. both are good, also depends on what C?B you want to run.

Kevin82693 · September 25th, 2009, 06:44 PM

well i was thinking about a flowmaster catback, but i heard that the regular o/r h pipe is louder than the prochamber, but i dont know if the tone is different and i know the prochambers have a nice deep tone

Muscletang · September 25th, 2009, 07:11 PM

What you have on your list should sound good. I have the Mac o/r h and it's nice. I have it with my Magnaflow cat-back which is notoriously quiet. It sounds good, but I'm thinking about switching to 40 series flows eventually for a little more of a growl.

Here are a couple vids. Not your year, but they essentially sound the same as your year.

thanks for these videos, the or h souds a little raspy, but its louder which is better (imo)

AMmuslGT · September 25th, 2009, 09:49 PM

prochamber will be deeper

SWEET2KSTANG · September 26th, 2009, 02:58 AM

the regular magnaflows are very picky about how loud they are with mid pipes. the tru-x, vrs, slp, and couple others make the regular magnaflows sound very very well. there are a few (BBK is one) that make the magnaflow's very quiet. i personally would never recommend flowmaster for anything, but thats me.

this is a friends mustang with VRS mid pipe, and regular magnaflow weld ins; thats it

i wanted prochambers, but now that ive heard both ill stick with the h pipe, i have weld in flowmasters 40

Kevin82693 · September 26th, 2009, 08:30 AM

ok, so ive been looking at the prochamber but i realized that they come with cats, but you can buy off-road legs for it...on mac's website, the picture of the prochamber (Pt# PC9600) already has one bolt on leg and one weld-on leg...if i get the off road legs, will i have to cut off the weld on leg and weld the new one on?

I know what you mean. It's not raspy on mine though. Here's the example I was looking at originally, but it's on a Cobra like mine though.

I'm glad you pointed this out to me. I may have to go with this.

Kevin82693 · September 26th, 2009, 08:43 AM

thanks, thats the sound im looking for, but i dont have long tube headers, i want them, but it would make it harder for me because ny's inspection stations are strict about the cat. converters...so im planning on swapping the new midpipe with the stock one when it comes time for inspection and the stock midpipe doesnt fit long tube headers

SWEET2KSTANG · September 26th, 2009, 04:22 PM

i didnt think mac was offereing the prochamber with cats anymore.

ModMustang97GT · September 27th, 2009, 04:56 AM

Lets be honest, the truth is, you want the best exhaust you can get. If you just wanted Loud you would get a uncatted Pypes X pipe with a set of Dumped Weld in LM1's. But that is not what you want.

You want the pro-Chamber, It is quite litteraly the best of both worlds. The volume and power power of the X, with the tone and Torque of the H pipe. Its hard to get much better than the pro-chamber over all, without going to a custom race piece.

I have seen flow chart numbers and power numbers, and I have yet to see anything beat the pro-Chamber on power and value.

Please post these reports. I've been around a long time and have never seen a Prochamber out-perform any other configuration. Although I have heard this several times I have yet to see any hard evidence.

Kevin82693 · October 2nd, 2009, 10:42 PM

thanks that sounds nice....when it says 5.4, is that the displacement? if so why is it not 4.6?

330CubeGt · October 2nd, 2009, 11:17 PM

Because i can't leave shit alone, lol

In the Video its a all motor 5.4 Hence my user name 330CubeGt.
330CI Being the Displacement.
