4-Inch Equal-Length Single Midpipe Valved Cat-Back Exhaust for BMW M3 G80 & M4 G82 S58
Upgrade your BMW M3 G80 or BMW M4 G82 with this complete S58 valved cat-back exhaust system, featuring a performance-focused 4-inch Equal-Length Single Midpipe design for a deeper, smoother and more aggressive exhaust note.
Manufactured from high-quality 304 stainless steel, the system provides excellent durability and corrosion resistance while replacing the factory exhaust layout with a freer-flowing performance setup.
The equal-length routing helps balance the exhaust paths before they merge into the large single 4-inch midpipe, producing a smoother and more distinctive S58 tone while improving exhaust flow through the center section.
The integrated electronic exhaust valves give you control over the sound using the included remote controller. Keep the valves closed for a quieter and more refined exhaust note, or open them at the press of a button for a louder and more aggressive S58 exhaust sound.
This BMW G80 / G82 performance exhaust is suitable for both standard and tuned vehicles and is designed for plug-and-play installation using the supplied clamps and factory-style mounting locations, with welding normally not required.
