AC Schnitzer Twin/Dual Exit Axle-Back

Transform your BMW 4 Series Gran Coupe F36 with a premium twin-exit rear silencer that looks stealthy, sounds purposeful and saves weight. This stainless steel sports back box features two 90 mm tailpipes, one on each side, finished in a tough black ceramic coating for a subtle OEM+ finish and outstanding durability. The result is a sharper, more athletic appearance with a deeper, more engaging tone that remains warranty-friendly.

We have supplied and fitted this setup for many happy customers and it remains one of our most popular performance upgrades for the 4 Series GC. It is supplied complete with a dark grey dual-outlet rear skirt insert where required, so you can achieve the twin-exit look without cutting the standard insert.
