Graham Rahal Performance

Porsche 911 Center Bypass Exhaust

911R/GT3/GT3 RS

Graham Rahal Performance has custom designed and manufactured a direct replacement for the secondary center muffler. Our exhaust is a great alternative to our Cup-style Side Muffler Bypass Pipes. By retaining stock side mufflers and valves, the factory "sports button" feature is kept to conveniently switch back and forth between the aggressive "sport" mode during spirited driving sessions and the quieter, more civil "non-sport" mode for minimal noise on the highway.

NOTE - GRP now offers a 13mm longer tip option for those 991.2 customers who want the tips to stick out of the rear bumper. The standard tip will be flush with the back edge of the bumper! Please note which option you would like at checkout!
