The RPi F90 M5 GTM Exhaust System utilizes our signature straight through design, and for the first time incorporates electronic valves controlled by the factory BMW servos. With the valves open, the system produces the familiar RPi "Bad Boy GTM" sound, with the valves closed, the sound level is on par with stock exhaust sound level. This system was specifically designed to complement the F90 chassis as the new M5 is a beast waiting to be unleashed! Put the M5 into Sport Plus, open the valves with the console button, and maximum performance is at your disposal. Power gains of 10-15 hp from 3.5k to 6k rpm on the full system.
The RPi F90 M5 GTM Exhaust System features include light weight 304 Stainless Steel construction, center X-pipe which replaces the factory resonator and a straight through rear valve design utilizing a resonator style muffler for valve-closed operation. With the valves in open position, the exhaust system is completely free of restrictions. The polished tips are 3.5 inch angled cut dual wall design. The 4 inch Black Edition Tips is also available as an option.
