Remus 081023 1510-5 BMW G80 G82 Racing GPF-Back Exhaust System (M3, M3 Competition, M4 & M4 Competition)

Remus Performance Rear Section - Part No. 081023 1510-5

Unlock the soundtrack and flow your BMW deserves. This Remus rear section upgrade for the latest G-series M cars replaces the factory rear setup after the particulate filter with a high-flow, valved performance system for a harder-hitting tone, sharper throttle response and stunning race-bred quality. Built from shot-blasted stainless steel and designed to mount on factory points, it delivers a serious step up in character without compromise on fitment.

We have fitted this system for customers and the feedback is consistent - superb build quality, a properly aggressive note when the valves are open and refined manners when cruising. If you want a premium sound upgrade for your M car with OEM valve control retained, this is it.

Why choose this Remus upgrade

• Valved performance rear section with centre pipework and front silencer replacement tube for a deep, motorsport-inspired tone
• Improved gas flow thanks to larger diameter pipework - OE 70 mm vs Remus 76 mm
• Low back pressure design for sharper response
• Lightweight stainless construction with shot-blasted finish
• Handmade in Austria with a perfect fit on factory mounting points
• OEM valve motors are reused for plug-in operation via the car’s electronics
• 24 month Remus warranty

Complete post-particulate filter rear section kit comprising the valved centre sport section, connection tube set with spherical joint, and the racing front silencer replacement tube.
