BMW M5 Performance Exhaust - Dinan Axle-Back Freeflow, Dual 3" Polished Tips (2000-2003). A purpose-built axle-back system that improves exhaust flow while delivering a refined, sporty note for your E39 M5.

Crafted from 100% 304 stainless with a 20-gauge muffler case, Dinan’s design employs Tuned Resonance Chamber Technology and drone abatement to balance performance and sound without harshness. The system weighs just 37.6 lb versus roughly 66 lb stock, trimming over 28 lb. Dual 3-inch polished, laser-engraved tips provide a clean performance finish, and factory brackets/hangers ensure straightforward fitment. When paired with Dinan software, gains of about +6 hp and +5 lb-ft at 6500 rpm are attainable.
