Downloadable Instructions Here

The absolute pinnacle in high quality single side out (SSO) exhaust for the KTM Adventure 950 and 990 is finally here from the leaders in high quality products and results. A no compromise, purpose built system for the true adventure enthusiast looking for the sought after 2 into 1 configuration with the highest in quality components, fit and finish.

Now choose from 'Standard' length (14" body) or 'Shorty' length (12" body) for a more compact fit and look. You can toggle back and forth in the pictures above of the 990 Adventure to get a good idea of what they look like. Please note that the shorter muffler will have slightly higher decibel levels and should be used in environments friendly to louder bikes. The sound is roughly the same as a stock motocross 450 bike. 


  • Over 16 lbs (7.25kg) in high / rearward weight reduction. Handling is dramatically improved.
  • Allows for the addition of an 'Endurocell' auxiliary fuel cell. (See here for more info).
  • Properly designed mid pipe with the correct area, convergence angles and exit tube calculations. This means NO restriction and better torque.
  • U.S. spec, premium 304 stainless steel, heli arc welded under a full purge of argon gas. (something rarely performed in production exhaust) This totally eliminate what is called 'sugaring', an inner rough and heavily scaled surface protrusion inhibiting exhaust flow commonly found on the inside most other systems.
  • Mated to a Yoshimura R77 14" muffler that is designed for large CC single sided sound reduction.
  • 18-8 stainless steel hardware included.
  • 2 size options: Standard 14" body or Shorty 12" body.
  • Optional Spark Arrestor (Added below or click here)

  1. Best mod to date 5 Star Review

    Posted by on 13th Oct 2019

    This system was easy to install and sounds amazing. Performance increase with a weight decrease one cant go wrong. I would advise to buy the graphite gaskets though trying to remove the old ones wasn't happening leading to a few days without listening to the new exhaust.

  2. very pleased 5 Star Review

    I've been looking at exhaust options for a while now. I'm glad I chose this! The stainless can looks great and now I can run an auxiliary fuel tank! It sounds incredible! Bit I will be purchasing the quiet insert, too loud for the neighborhood. Thanks for selling a quality product that fits amazingly!

  3. fantastic quality. 4 Star Review

    Posted by on 23rd Jul 2017

    First, I'm a big fan of Rottweiler Performance, and have used the filter kit with Akrapovic cans without DB killers on my 950SM. Perfect combo.

    This year I changed to a 990 Adventure, and like many others I wanted a 2-1 single side out exhaust.

    The 2-1 pipe is a work of art, perfect fit and finish. The Yoshimura pipe looks fantastic(I went for the long version) and sounds fantastic.

    Even with DB killer inside its a little louder than my old Akrapovic cans without db killers. must mention that the Yoshimura works perfect on highway speeds, even without DB killers it's comfortable.

  4. Barks like a Rottweiler 4 Star Review

    Puts a smile on my face every twist of the wrist. Its much lighter than the stock setup. Well built, worth the money.

  5. top notch fit and performance 5 Star Review

    Posted by on 13th Jan 2017

    I really studied this purchase, as I've had my 990 since 2013. Had wanted and ordered fmf, but after waiting 6 months on backorder realized they were not coming. Im glad they didn't, I always liked the dual pipe look,but after much thought I pulled the trigger on the sso system. I couldn't be more satisfied, which is rare for me. Install was straight forward, did not locate instructions or a video, but fit up very snug and factory. Looks and sounds great, I chose to run dB killer,not to much louder than stock. Gives bike a high performance sound and a noticeable gain in throttle response. I haven't changed mapping, seems happy.Also weight loss is amazing. Quick ,professional shipping and service,definitely recommended!

  6. Exceeded My Expectations 5 Star Review

    Perfect fit and finish. The quality of Akropovic from a small company. Very happy with the sound and performance as well. Overall a very satisfying purchase and highly recommended for the adventurer.

  7. only SSO exhust you should buy 5 Star Review

    Posted by on 21st Apr 2016

    Recently put the SSO on my 990 and the craftsmanship of the mid pipe is superb. I am an extremely picky person when it comes to fitment and build quality and Rottweiler did not disappoint. Honestly it's the best fitting aftermarket part I have put on my 990 to date. I plan on running some of their other parts soon.

  8. Nice Work Rottweiler 5 Star Review

    Finally, a system that's made to accommodate the Hepco/Becker cases. It was easy to install, the fit is perfect and it looks great. I noticed the reduction in weight the first time I took it off the stand. Ran it with and without the baffle, and decided on better low-end throttle response and lower noise level.
