Barker's Quiet Cores are manufactured in two different sizes, a 1 inch and a 1.5 inch. Every Barker's exhaust uses the 1 inch version except for the snow mobile systems. For snowmobile sleds you MUST choose the 1.5 inch, as the 1 inch quiet core is not compatible with these systems. All quiet cores include a spark arrestor.
Quiet cores are sold individually, so if you have a dual exhaust you will need to purchase two quiet cores.
The Barker's exhaust system quiet core is designed to reduce the decibel output from your Barker's exhaust system. The 1 inch quiet core fits all of the current Barker's exhaust systems that feature an exhaust can (except the sled systems), so it can be added to your system even if it was purchased years ago. Note that a quiet core can result in a slight loss of 0.5 to 1.5 horsepower. In some regulated areas, a quiet core is required. Please check your local ordinances and don't hesitate to contact us if you have questions.
