Description: MAC's new patent pending PRO CHAMBER has just obsoleted the competition's H-pipe technology. 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 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 the exhaust pulse and flow, resulting in more power and economy.

MAC's PRO CHAMBER goes even further than traditional H-pipes to produce more torque and horsepower by merging exhaust pulses in one area. Merging of all exhaust gases creates higher temperatures which creates a boost in exhaust velocity, plus lets exhaust gas see both outlets.

Pros: very loud and growling
Cons: crappy paper gasket

The SOTP feeling was awesome from the very first time I drove the car after it was put on. Now they\'re making them with cats so it\'s smog legal, even better. With a good set of mufflers, you\'ll have a car that can be heard well before it\'s seen. I can\'t atest to the \'Dura-Black\' coating they\'re putting on them now but the aluminized stuff they were doing didn\'t do much to prevent rust though. Also the big fat paper gasket that comes with it needs to be thrown away and an OEM gasket used on installation.

Pros: Awesome sound, easy install
Cons: weak paper gasket.

The sound is awesome, very loud rowdy and raspy. There\'s no sneaking anywhere with this mid-pipe, even with stock mufflers still installed.
