COVID-19 UPDATE: Starting March 30th we will begin shipping orders once a week for IN STOCK items only. We have set up an automated phone service that will allow you to speak with a sales representative during this time, if needed. We thank all of our customers for working with us during this time and look forward to returning to full production in the coming weeks.

How to Measure your Pipes

1. Measure the inside diameter (ID) of the pipe at the exit end that you are installing the baffles in. (If installing into the head pipe, please measure the inside diameter (ID) of it as well.)

2. If removing existing baffles, measure the outside diameter (OD) of your existing baffles.


4. If you have gutted your mufflers or removed your stock baffles call and ask for a tech person, 704.847.1222.

(Diameter: The distance across a circle.)
