ARM Motorsports Race Exhaust For E82 BMW 135i Coupe

If you're looking to transform the sound of your 135i, The ARM 135i Race Exhaust is for you!  The ARM 135i Race Exhaust is designed to open up the sound of your 135i by removing the secondary catalysts, resonator, and muffler found in the OEM 135i setup.  These elements of the OEM 135i exhaust hit the mute button on your 135i.  The ARM 135i Race Exhaust turns up the volume on all the incredible sounds hidden by the OEM 135i exhaust.  After installing the ARM 135i Race Exhaust you will experience all the snarl under load, whistling turbo sounds on deceleration, and raw roar on full throttle that your 3.0L inline six has to offer!  The ARM 135i Race Exhaust is direct bolt-on system, and designed for a direct fit with the ARM N55 Downpipe, N54 Downpipes, or OEM downpipes.

Construction:

The ARM N55 135i Race Exhaust is built with high-grade TIG welded SS304 stainless steel.  The ARM 135i Race Exhaust includes a front midpipe, rear midpipe, axle back section, exhaust tips, as well as installation hardware and gaskets. 

It begins with a precision CNC machined flange at the downpipe which is a direct fit with the ARM N55 Downpipe, ARM N54 Downpipes, OEM downpipes, and many upgraded downpipes. This first section of the midpipe is a divided design comprised of two 2.5" sections. 

The second section, the rear midpipe, continues the divided design until the axle back connection where a Y-pipe merges both pipes into a single 3" pipe.  The final section of the ARM 135i Race Exhaust is the axle back component and this single 3" pipe continues all the way until the driver size bumper exit where you have the choice to finish off your ARM 135i Race Exhaust with either the Sport Silver or Stealth Black exhaust tips.
