BMW G82 M4 Performance Cat-Back Exhaust System

SKU G82-M4-PEXH
Price

$2,124.99

This performance cat-back exhaust system opens up exhaust flow behind the catalytic converters on your BMW G82 M4, giving the S58 twin-turbo engine a freer path to breathe and a more aggressive exhaust note.

Purpose-built for the G82 M4's S58 exhaust flange layout, it's designed as a direct bolt-on replacement for the factory system.

This is a proven upgrade path among M4 owners looking for more sound and marginal flow gains — built with durable materials suited to the heat and pressure a high-output turbo six produces.

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
