The Turner Race Inspired exhaust deletes the rear mufflers in the F10 M5 to allow more of the exhaust sound to be heard. Turner loves their M5 but it's just too quiet so they looked at ways to get more of the stock exhaust to be heard. After evaluating the stock exhaust layout it was easy to see that removing the rear mufflers would accomplish what was wanted. But cutting the mufflers off is just the beginning. They then had to develop a set of pipes and design a set of tips that fit perfectly and also looked right at home on the M5 super sedan. And these M5 muffler delete pipes are the finished product.
The Turner axle-back exhaust is made from a 304 stainless steel tube in the same diameter as the stock exhaust and with mandrel bends for unimpeded flow. It fits with the stock hangers and is clamped to the stock exhaust pipes once the mufflers are cut off. And the entire installation can be done in about an hour with the exhaust on the car. With factory clamps, you can easily reinstall your stock mufflers at any time. The optional tips are also stainless in a perfectly proportioned 89mm (3.5" diameter). They fill out the rear bumper valence perfectly - not too small like stock and not boy-racer large. Tips are available in mirror silver or brushed aluminum.
The final result is that removing the stock mufflers really lets the M5 V8 sing! With the mufflers and flapper valves removed the sound on start-up is scintillating. The sound from the S63TU engine is robust and intoxicating - it just needs to be heard! From outside, the muffler-delete exhaust makes the car seem all the more impressive. From the burble at idle to the roar under full throttle there is little doubt that this is a proper M car. Inside the car during normal driving the sound is not changed much thanks to the Active Sound Design system. It's a little louder but not intrusive or irritating. Around town the car sounds much like stock but just a touch louder. The exhaust pops and burbles more with each downshift. On the highway at 70-80 cruising speeds it's as quiet as a muffled exhaust.
