Turner Motorsport Valved Performance Exhaust - BMW F8x M3/M4 S55 (MUST CHOOSE TIP STYLE FROM MENU BELOW)
Our Valved Performance Exhaust System replaces the restrictive factory axle-back with a high-flowing, valved stainless steel muffler. The result is a deeper, more aggressive tone when you want it and a refined, livable sound when you don’t.
Each system starts with mandrel-bent dual 2.5" 304 stainless steel tubing. Mandrel bending keeps the pipe diameter consistent through every bend, which maximizes flow and keeps the system resistant to corrosion and heat for years of hard use. The high-flow muffler keeps the valved design, so you still get a quiet mode for cruising and a fully open note when you put your foot down. Unlike many aftermarket designs, both muffler exits are put to work for valved and muffled flow, so all four tips are active, and you get a full, balanced sound from every outlet.
Installation is a direct bolt-on. The axle-back connects to your stock mid-pipe using Accuseal slip-fit joints for a tight, leak-free seal, and it hangs from the factory exhaust hangers, so no cutting or modification is needed. The 2.5" muffler exits fit a wide range of tip options, and the system ships with TURNER-engraved 4" brushed stainless steel tips for a clean, OEM+ look.
