MAC's 3 piece Pro Chamber Design allows you go from Street Legal to Full Race in just about 1hr-2hrs. The MAC PC2605 can be bolted to the Stock Catalytics or the MAC Off Road Legs. This is a Great Up Grade for the Weekend Racer. Keep your Mustang Street Legal when driving around town and on the weekend go all out with a Off Road Racing Exhaust System on the Track!
Designed for True Dual Exhaust! The MAC PC2605 will allow you to use MAC Short Tube Headers, OEM Stock Manifolds and most other aftermarket Short Tube Headers. This system will also require the use of a GT Style Cat-Back System (MAC Part # TK4605) to complete the exhaust system.
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!
