Milltek Sport Rear Exhaust Upgrade for BMW M3 E92 4.0 S65 V8 Coupe 2007 to 2013 — Part No. SSXBM941_1

Unlock the full character of your S65 V8 with this premium rear section system from Milltek Sport. Crafted in the UK from high grade 304 stainless steel with constant-radius bends for superb gas flow, this direct replacement transforms sound quality, sharpens throttle response and adds long term durability to your BMW M3 E92 Coupe. If you want a refined motorsport tone with everyday comfort and zero unwanted cabin boom, this is the upgrade enthusiasts choose.

The pipework, silencers and hardware are built from non-magnetic 304 stainless to resist corrosion and discolouration, delivering a clean fit and robust finish that lasts. Flow paths are optimised to maintain mid-range torque while freeing the V8’s upper rev character. The result is a deeper cold start, crisper acceleration notes and a mature soundtrack on the motorway.
