Supersprint LH Left Rear Silencer/Muffler Back Box – Axle-Back Exhaust for BMW M3 F80 & M4 F82 F83 S55 | Performance Rear Section | Part 047934

Supersprint Left-Hand Rear Silencer for BMW F80 M3 and F82 F83 M4 | Part 047934

Give your S55-powered M car the soundtrack it deserves. This genuine Supersprint left-hand axle-back unit replaces the factory rear box on the driver’s side, unlocking a sharper, more motorsport-led tone and a less restrictive exit path. Ideal for enthusiasts who want a louder, crisper note on road and track, with precision fitment and the premium finish Supersprint is known for.

We have fitted this to customer builds and the feedback has been outstanding. Expect a more engaging growl, faster-revving feel and a proper performance character without the compromise of poor fit or drone from cheap alternatives.

Key reasons to choose this upgrade

• Direct replacement left rear box for F80 saloon and F82 F83 coupe and cabriolet models
• Less restrictive gas path for a sharper, sportier sound and improved response
• Axle-back left-hand section that integrates with the original system
• Genuine Supersprint quality with a 3 year warranty
• Proven on customer cars. Excellent fit, excellent tone, excellent smiles per mile

Note. This listing is for the left-hand rear section only. For a balanced twin-exit setup, pair with the corresponding Supersprint right-hand rear module.
