We at Sonic MS are proud to introduce RPi's GTS Axle Back Exhaust System for the E70/E71 X5/6 M.
RPi X5M/X6M GTS Axle Back Exhaust
MFG PN [RP-EG026]
It's proudly crafted in the United States out of high quality T-304 stainless steel, and saves approximately 20 lbs from the bulky OEM equipment. Comes with all the hardware for a bolt on installation. In addition to giving your S63 engine an intoxicating sound, this exhaust system alone shows gains of approximately 10-15hp and 10-12 ft/lb of torque. Expect 60whp + gains with a complementing ESS tune.
RPi was able to make the market's first true straight through muffler system for the S63 engine. Other exhausts on the market utilize a sine in/dual out with a chamber in the center due to a lack of space. RPi's GTS exhaust system is a straight through design that will offer superior performance over a chambered system.
