MAC Prochambers!!!!!!!!

huggy bear · December 16th, 2009, 01:52 PM

So I hear alot about these and all I hear is really good things so I do have a couple q's. You can get them catted or uncatted correct?? Which header(s) will it comply with? Also about headers I understand that as far as HP gain goes they don't help any at all so are they worth it? Will my stock headers work witht he MAC Prochamber?

prochamber will work with stock manifold
as far as i remember a prochamber is o/r only,no cats.the chamber part act like a cat but not,(hard to explain
LT headers will help a little but more for sound
best fit mac LT and MAC prochamber
for stock headers

nevermind i just seen that they are a catted prochamber

MAC’s patented PRO CHAMBER® has obsoleted the current intermediate systems. Split (one each side) manifolds
or exhaust headers on any engine need to be balanced to each other. On a V-8 motor for example, exhaust pulses enter
respective collectors at uneven intervals of 0-90-180-270 degrees of engine rotation. This process hampers the full
benefit of any exhaust header or manifold system by the long intervals between exhaust pulses, making balancing of
exhaust mandatory for optimum power. Balance tubes between exhaust, on opposite sides, help transfer exhaust
pulses from side to side to smooth out exhaust pulses and flow. This results in more power and broader torque band.
MAC’s PRO CHAMBER™ goes even further than traditional X & H-pipes to produce more torque and horsepower
by merging exhaust pulses into one area. Merging of all exhaust gasses creates higher temperatures which creates a
boost in exhaust velocity and allows exhaust gas to use both outlets.
Your exhaust will think it’s a 180 degree Tuned Header! “Big HP”

I Love my Pro chamber

dcook_14 · December 16th, 2009, 03:45 PM

Yeah you can get catted prochambers to fit short or long manifolds/headers. Prochamber is probably a step up in HP from the stock H-Pipe, but probably not any more so than the other midpipes. LT's can add some good HP if you're supercharged for sure. I can't wait to build my motor and stick some MAC LT's and a catted prochamber on there

I love mine too

LGHTNG02GT · December 16th, 2009, 05:19 PM

ProChamber > every other midpipe

i had a regular h, an x and then a prochamber and wouldn't give up my MAC for anything!

rider4life350 · December 16th, 2009, 07:41 PM

prochambers are awesome
