Leo Vince LV-One EVO II KTM SM 990 / 950 / Supermoto / R

The Leo Vince LV One EVO II Slip-On Exhaust is the entry level exhaust in the LeoVince line and is built on the success of the SBK Factory range. Similar in shape to the original LV ONE, the EVO II has taken a leap forward with the use of the most modern materials and a redesigned end-cap. The end-cap is constructed of a techno-polymer that is both durable and heat resistant. Gone are the days of a square muffler inlet cap, the LV One EVO II incorporates an aerodynamic inlet cap to reduce drag and increase its sporty appeal. Last but not least it features that distinct LeoVince performance and sound that will enhance your motorcycle’s power output throughout the entire RPM range.

Two options are available for most models: stainless steel and carbon fiber. The stainless steel features ASIS 204 stainless steel with a special sandblasted finish giving it a titanium-like look. The carbon fiber option is the lighter than stainless steel and features a flat finish that exposes the intricate carbon fiber weave.


  • CAD/CAM design for precise fit
  • Techno-polymer end-cap
  • Weight savings over stock exhaust
  • Increased horsepower across the entire RPM range
  • TIG-welded AISI 304 stainless steel link pipe
  • Tuned to work with stock fuel settings

Note: Leo Vince Exhaust no longer features the "Leo Vince SBK" logo, please reference image #1 for the current exhaust logo.

LeoVince makes Prince, but not quite King
After a month of use my overall satisfaction is pretty good. There were not very many options for the 950SM and I will admit a primary factor in choosing Leo Vince was cost.

Good: over all packaging was excellent. Every item was separated and bagged and well protected.

Good idea but encountered problems: The y pipe comes in three pieces to allow flexibility at each slide joint to line everything up correctly. The problem was the metal is very thin and once assembled did not want to turn or slide. Had to remove and reassemble multiple times which caused the metal to flex and bend. As well made as each piece was it was very surprising it didn’t assemble smoother. The connections were sanded and oiled to ease in slipping together and to allow turning but once assembled things did not want to move correctly. A great deal of force was necessary to bend things into correct placement to ensure each muffler was positioned at the same height. Once everything was tightened up however, it all looked very good. Just hope you don’t have to remove it. I will give Leo the benefit of the doubt that with the quality of appearance of their parts, the installation problems might not represent the average experience.

Cost: even at the discounted price it was hard to be pleased with stainless mufflers costing over $600. RevZilla did offer the cheapest price I found, and that is always a plus.

Noise: Immediately noticeable over stock. Sound is clean and not over bearing (db killers in place). Makes appropriate roar at upper rpms to scare children and small animals.

Performance: Surprisingly there was not a big noticeable difference in power. Bike ran cooler and carburetor rejetting was not immediately required. With the addition of an open air filter system however the power increase was dramatically improved.
