Details

Ford Mustang 5.0L V8 1979-1993 2½" Aluminized Steel Off Road Pro Chamber to MAC Long Tube Headers. For 5Speed Transmissions Only

 The MAC Patented Pro Chamber™ has made the current intermediate systems obsolete all together. Split (one each side) manifold or exhaust headers on any engine, need to be balanced to each other. On a V8 motor for example, the exhaust pulses enter respective collectors at uneven intervals of 0-90-180-270 degrees of engine rotation. This process hampers the full benefits of any exhaust header system or manifold by the long intervals between exhaust pulses. Balancing of exhaust gases in mandatory for optimum power. Balance tubes between exhaust, on opposite side, helps transfer exhaust pulses for side to side to smooth out the exhaust pulses and flow. This results in more Power and a broader Torque band.

 The MAC Pro Chamber goes even futher than the Traditional X & H-Pipes to produce More Torque and Horse Power by merging the Exhaust Pulses into one area. Merging of all Exhaust Gases creates Higher Temperatures which creates a Boost in Exhaust Velocity and allows the Exhaust Gases to see and use both Outlets.

 Your Exhaust will think it's a 180° Fully Tuned Header!
