RK Titanium Super Single Exhaust – BMW F8X M3/M4/M2 (S55)

RK Titanium Super Single Exhaust System – BMW F8X M3, M4 & M2 (S55)

Introducing the RK Titanium Super Single Exhaust System for the BMW F80 M3, F82/F83 M4, and F87 M2 Competition.
After dominating the B58 Supra and G8X platforms, the iconic RK Super Single design is now available for the S55 engine—bringing the deep, pure, aggressive tone the F8X platform has been missing.

Deep, Throaty Sound Without Rasp

Say goodbye to mixing and matching midpipes and rear sections to fix S55 rasp.
The RK Super Single is engineered as a complete system to deliver:

• A deep, resonant tone

• Zero rasp

• Clean turbo spool and crisp throttle acoustics

• A signature JDM-inspired single exit

This is the sound the S55 should have had from the factory.

Ultra-Lightweight Titanium Construction

As one of the lightest S55 exhausts ever produced, the RK system features:

• 16 lbs (Signature w/ resonated midpipe)

• 13 lbs (Signature w/out resonated midpipe)

• 9 lbs (Track Edition straight pipe)

Each system utilizes straight-through 3.5” titanium tubing, merging from factory-downpipe flanges and routing cleanly to a 4” pie-cut titanium tip.
