D660-4604 – Dinan Free Flow Exhaust for BMW M3 E46 2001-2006

If you’ve been searching for a truly high performance rear muffler for your M3 look no further. Dinan’s unique muffler design effectively reduces back-pressure for improved flow, resulting in measurable power gains. Manufactured from 304 stainless steel inside and out for superior resistance to corrosion as well as a significant reduction of weight. And from those aggressive looking ceramic-coated tips flows an exhaust note that will be music to the driving enthusiast’s ears.

The Dinan exhaust delivers exactly what the M3 owner demands in a performance muffler; increased power, reduced weight, a look that means business and the throaty exhaust note you’d expect from an M3.
