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.

    I have a John Deere Diesel engine about 50 hp that drives an agricultural pump. Several years ago I purchased from John Deer a residential muffler for the engine it is now in need of replacement and I want to do better this time. I would prefer maximum noise reduction, I live approximately 1500 feet from this engine and the sound bothers me especially at night. Will your product provide some relief ?

  4. Jeff says:


    Will your Super Trapp Quiet Muffler work on a Perkins 402C engine? It would need to either clamp to a 1 1/2″ exhaust pipe or attach to the 2-bolt flange on the flexible exhaust pipe

    Thanks! Jeff

    I have a Honda gcv 160 over head cam motor on my cub cadet wood splitter. Would your super trap muffler work on this and if so which one? I am looking for the quietest one you have.

  11. Bill says:

    I have a 18.5hp Craftsman Riding Lawn Mower that I want to make quiet. Do you have a muffler that can bolt up to it. The current muffler is on the lower front of the mower…

    Have a Husky ohc GCV190 power spayer that is a few years old and in excellent condition. Would like to make it quieter for my neighbors, as I enjoy using it. What SuperTrapp muffler do I need? A 3S with two discs? I guess I do not need the resonator as my muffler is still good. Is it easy to install? R
