This dual port muffler will increase cutting speed and help keep your engine cooler than the OEM muffler. Works great for stratified as well as non stratified engines.

 The exhaust ports direct hot exhaust gases and fumes in a direction safe to the operator and work.

 I have sold hundreds of these mufflers in my 372XP listing.

 Exhaust port size is 3/4" inside diameter. I offer this very same muffler with smaller 5/8" inside diameter ports also.

 Muffler contains no spark arrestors. Rubber plugs are included to close ports while saw is not in use. No returns. I use USPS Priority Shipping.

 If your Jonsered saw has a muffler that fits a Husqvarna 372XP, then this muffler will work on your saw.

 This is an easy bolt on method to obtain the extra in your saw.

 International shipping to many countries.

 I have been producing and selling performance based high flow chainsaw mufflers since 2018.

 If any of MY mufflers fail due to my workmanship, I will repair or replace the muffler free of charge to the original purchaser. Buyer pays return shipping only.

 Please see my other items.

 Thank you for your interest.
