Supersprint Supersprint "Racing" lightweight exhaust for BMW M3 (E46)

Unlock the S54 soundtrack and sharper response with a race-bred rear section built for true enthusiasts. This Supersprint rear box delivers an open, perforated core path that massively reduces exhaust resistance compared with the factory unit, unleashing a hard-edged motorsport tone and real weight savings at the very back of your E46 M3. It looks the part too, with four beautifully aligned tips that sit perfectly with both the standard rear bumper and the CSL diffuser.

Why enthusiasts choose this upgrade

• Free-flow internal design for minimal gas resistance and improved breathing
• Pairs brilliantly with Supersprint tubular manifolds and centre sections for a complete system
• Authentic track-bred character with an aggressive, crisp note
• Low mass construction that still offers exceptional durability
• Hand crafted in Italy with meticulous attention to fit, alignment and finish
• Quad exit layout positioned for both OEM M3 and CSL rear valances
• Accurate fitment to factory mounting points for a straightforward install
