SRT8 cat-back exhaust

Corsa cat-back system for the Grand Cherokee SRT8

In August of 2006 Mopar released a performance cat-back exhaust system for the Grand Cherokee SRT8. The exhaust upgrade was designed and built by Corsa Performance Exhausts under the direction of the SRT8 team and was specifically tuned for this vehicle.

Sold by both Mopar (p/n P5153453) and Corsa (p/n 14451) it has a retail price of $1385.00. Installation is fairly easy as it is a bolt-on system with no welding required. If ever desired the stock components can be easily reinstalled in the future. Muffler or performance shops typically charge around $75 to $100 for the installation.

The main advantage over the Corsa system vs other cat-back systems for the Grand Cherokee is the fact that the system produces no drone, very important criteria for most owners.
