Installing Rotax Ricks 670 Muffler on a 670

26 posts in this topic


It's really not that much bigger. It would easily fit with my set up but my cowl has been hacked on a lot over the years. If you look at this exhaust compared to the 670 snomo it's tiny and another reason why it's not making nearly the horsepower. The proper exhaust is critical to making a 2-stroke run properly. It's totally different than a 4-stroke.
