Dinan Free Flow Axle-Back Exhaust System for BMW M5 2006-2010

The Dinan M5 Axle-Back Exhaust System is engineered to optimize airflow and maximize power gains while delivering a refined yet sporty exhaust note that remains appropriately aggressive during wide-open throttle conditions. Unlike many aftermarket mufflers, this system eliminates the annoying low-RPM drone, ensuring a pleasant driving experience. Constructed from 100% 304 stainless steel, both inside and out, this exhaust system boasts exceptional corrosion resistance and a nearly 30% weight reduction, shedding over 20 lbs from the original setup.

Featuring four 3.5" diameter polished or ceramic black stainless steel tips, the Dinan exhaust not only enhances the aggressive aesthetic of the M5 but also incorporates Dinan’s innovative "Cool Tip" design. This unique feature reduces temperatures to minimize radiant heat that could harm the bodywork over time and prevents discoloration of the tips. The Cool Tip design utilizes a rarefaction principle, with an inner and outer tip and a vent at the base to draw in surrounding air, effectively cooling the tips and reducing the risk of burns while loading the trunk. Utilizing factory brackets and hangers, the Dinan exhaust ensures a seamless fit and straightforward installation.
