P1 GT2 Valved Exhaust System

BMW G80/G81 M3 & G82/G83 M4 | S58

The GT2 Valved Exhaust System is engineered to bring out the true character of the BMW S58. Featuring a 2.75-inch mandrel-bent Z-pipe mid-pipe and a free-flow, non-resonated design, the GT2 delivers a deeper, more aggressive exhaust note with enhanced turbo sound, crisp overrun, and pronounced gear-change character.

Designed to work seamlessly with either factory OEM downpipes or high-flow catted downpipes, the GT2 gives enthusiasts the flexibility to enhance exhaust flow and sound while maintaining the configuration that best suits their build.
