Super Trapp Quiet Muffler Selection Guide
For exhaust silencing, you must use the optional resonator.
Use the 3s Models if space is limited. The 5s models are the quietest when equipped with the optional resonators. Three types of 5s resonators are available, 4″, 5″ tri-tube and 6″ tri-tube. With the 6″ tri-tube being the quietest. This is a retro-fit muffler that can be used on most gas, diesel and 2 cycle engines. Many engines have an exhaust port that is threaded with National Pipe Threads (NPT). It is just a matter of removing your existing muffler and inspecting the exhaust port. The threaded (npt) models listed on the 3s and 5s pages can be screwed into those engines. Please note that all the available information on these mufflers is contained on our web pages. This is a retro-fit muffler, we can not offer any further suggestions in the application or use of these mufflers than what is listed on our web pages.
