Dinan Free Flow Axle-Back Exhaust - BMW 328i / M3 (E36) 1992-1999 - Polished Tips

Dinan's Free Flow exhaust opens up the restriction in the factory muffler without the boom that usually comes with it, using a Tuned Resonance Chamber inside the case to cancel the frequencies that cause cabin drone while still letting the car sound sharper. The whole system is 304 stainless with a 20 gauge muffler case, and it weighs just over 17 lb against 28 lb for the stock muffler, so 11 lb comes off the back of the car. Paired with Dinan software the gains run from 6 hp and 5 lb-ft on the 328i up to 11 hp and 13 lb-ft at 4500 rpm on the 325i, with the 1996 to 1999 M3 picking up 9 hp and 7 lb-ft at 6500 rpm. It hangs on the factory brackets and hangers, and it exits through dual 2.5 in polished and laser engraved tips.
