The Mopar Performance cat-back exhaust system features T304 2.25" stainless steel (aircraft quality) construction with mandrel-bent tubing, stainless band (Torca) clamps, and polished 2.125" dual wall tips.
This free-flow system provides a horsepower and torque gain while improving fuel economy, and is CAD designed and dyno tested for optimal performance and sound.
When installed with the Mopar Tubular Exhaust Header (MP5153566) and Mopar Cold Air Intake System (MP5153572) the system yields an over 10 hp gain (measured at front wheels).
