Wolf Line Rear Muffler for BMW M135i and M235i N55

Give your F-series six-cylinder BMW the soundtrack and response it deserves with this Austrian-crafted rear section from the Wolf line. Built in shot-blasted stainless steel with a free-flowing core, this performance rear box unlocks a richer, deeper tone, sharper throttle feel and lower back pressure while maintaining everyday usability. It bolts straight to the factory hangers for a clean, hassle-free install and a perfect fit on the N55-powered hatchback and coupe platforms.

We run this setup on customer cars and our own builds. Feedback is consistently strong on tone, quality and fit. If you are chasing a premium BMW hot hatch or coupe exhaust note without compromise, this rear muffler delivers.

Why this Wolf line rear section stands out

• Track-inspired sound with a deep, sporty character
• Shot-blasted 100 percent stainless construction for longevity
• Free-flow design helps reduce back pressure for improved response
• Weight-saving layout with precise fitment on the F20 F21 F22 F23 chassis
• Bolt-on using factory mounting points, no cutting of hangers required
• Crafted in Austria with premium workmanship and finish
• Backed by a two-year Remus warranty

Configure your system

This rear silencer forms the tail section of a modular performance system. Choose how far you want to go with your N55 build:

Rear section kit - Pair this silencer with a compatible tail trim set to complete the axle back assembly.

• M135i tip options: black or chrome finish
• M235i tip options: black or chrome finish

Cat back - Add the matching front silencer to create a full-length system from the catalytic converter for a louder, fuller tone and improved flow.

Turbo back - Combine with a 200 CPSI racing downpipe and the front section for a complete system from the turbocharger for maximum performance potential.

Prefer a quieter, homologated solution for road use in certain regions. A Sport version with EC approval is also available for the same models.
