AC Schnitzer Valved Quad Exhaust Axle-Back for BMW M4 F82/F83 - Matte Black 90mm Tips - Performance Back Box Muffler Tailpipe Upgrade for S55 Coupe & Convertible

Transform the rear of your BMW M4 F82 and F83 with a premium quad exit performance exhaust upgrade in a stealth matt black finish. Crafted by AC Schnitzer, this rear section delivers a richer, more purposeful tone, a lighter setup compared to the factory unit, and a bolder look thanks to four 90 mm outlets that fill the diffuser perfectly.

This valved system keeps your OE flap control, so you can enjoy calm cruising when you want and a more assertive soundtrack in dynamic driving. Built from high grade corrosion resistant steel, it is made to withstand UK roads while elevating both sound and style on your M4 Coupe or Convertible.

• Quad 90 mm tips in stealth matt black for a discreet motorsport vibe
• Also available with mirror polished chrome tips if preferred
• Retains factory valve control for comfort and sport modes
• Weight saving over the stock rear box for improved response
• Engineered for the F82 and F83 chassis for precise fitment
• Deeper, more characterful exhaust note with enhanced presence

Looking for even more volume and flow? The optional Export version adds centre link pipes with high flow sports catalysts to further open up the S55’s soundtrack while reducing back pressure for improved breathing.

We run this upgrade on customer cars and it consistently impresses with its quality, finish and valve-controlled versatility. Drivers love the way it sharpens the M4’s personality without sacrificing everyday usability.

Pair it with the matching carbon fibre rear diffuser, available separately, to complete the aggressive quad exit look.
