Exhaust gasses are guided through 3-inch diameter tubing into the center inlet of the fully-24-inch wide muffler section. Internal to the muffler, the exhaust gasses pass through a reversed Y merge, efficiently splitting the exhaust into separate muffling chambers on each side of the canister. 2.5-inch outlets emerge symmetrically from each side of the canister and direct the exhaust out the rear through quad polished exhaust tips.
Significant attention was devoted to the packaging of this exhaust. Tubing diameter was increased to 3" and bends were kept to a minimum with large radii for optimum flow characteristics.
Designed as a direct replacement for the factory cat-back exhaust, the new COBB Cat-Back exhaust system for the Mitsubishi EVO X has been completely redesigned to improve the look, sound and performance of this system.
The PERRIN Dual Tube Catback Exhaust is designed for high performance, long life, and great sound. Splitting the exhaust flow into two tubes creates a higher flow capacity and a unique sound for your Subaru boxer engine.
This exhaust features a true 3.0 all the way through mid-pipe that connects to the rear section splitting into two 3" pipes and finished off with quad 3.5" tips.
The muffler inside contains continuous piping design and use of Advantex material that results in an excellent free-flow exhaust with optimized back pressure, giving greater horsepower, torque gains and a rich deep sporty sound.
