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" carbon fiber 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) (Note: spark arrestors can be hard on carbon fiber body mufflers if run continuously for long periods of time. If it is necessary to run full time, you may want to look into the stainless SSO kit here. See the notes on the spark arrestor page here)

  1. SSO on an ‘04 950, couldn’t be happier! 5 Star Review

    Posted by on 6th Oct 2019

    Fit and finish is incredible, not one bolt was misaligned after install, including my frame mounted pannier racks. WAY more sound than I was expecting, so be wary. I love loud bikes so I am going no quiet insert. I went with the carbon 14 and it has an extremely aggressive and deep tone. It is definitely loud enough even at idle to drone out the annoying clanking of the LC8 motor. Weight savings is tremendous and instantly noticeable when whipping the bike through trails. Main reason for me getting this exhaust was to cool the running temps down. Works 100% in that regard, bike runs much, much cooler. Aux fan barely ever kicks in now, even when ringing the bike out on a long, technical uphill. I was on the fence as to which yosh to get. One phone call and a great conversation later, Rottweiler Performance got me all sorted. Professional folks making fantastic products and fast shipping to boot! If I come across any other part I have interest in, I’m working with these folks first!

  2. OUTSTANDING in EVERYWAY 5 Star Review

    Have now fitted the full Rottweiler Air Intake System, Factory Pro jetting kit, Flex Jets, Snap Out 60 Second filter change bracket and to finish the system just installed the SSO Carbon Yoshi Exhaust, what can I say the 950 is Finally Awake. The quality of all components are fantastic the best the whole system was not overly difficult to fit and and every fit was perfect. The bike has been taken to a new high level and is outstandingly responsive, the Grin Factor hurts my face. anyone who owns a 950 and has not installed the system is missing out BEST thing I have done with the bike so far. Thankyou to the Rottweiler Team. From mike
