AC Schnitzer Quad Exit Sports Exhaust for BMW X3 F25 (2010-2017) - 4-Tip Performance Backbox/Muffler, Stainless Rear Silencer, 90mm Black Ceramic or Chrome Tailpipes - fits petrol & diesel, quad conversion

Transform your BMW X3 F25 with a premium four-outlet rear system

Upgrade your BMW X3 F25 with a genuine AC Schnitzer performance rear section featuring four 90 mm outlets for a purposeful, factory-plus look and a richer exhaust note. Available with ceramic black coated tips or bright chrome tips, this high-grade stainless rear box gives your SUV a sharper presence and a refined tone, while saving weight over the stock setup.

Why choose this upgrade

• Four-outlet design for a bold, motorsport-inspired rear end
• Stainless construction for durability and corrosion resistance
• Choice of tip finish - ceramic black or polished chrome - both in 90 mm diameter
• Lighter than the original rear muffler for a more responsive feel
• Smoother flow for improved breathing and a richer, sportier soundtrack

On diesel variants, the sound enhancement is intentionally subtle for everyday refinement. Cutting guides are included to neatly trim the rear valance for the quad-exit layout.
