Overall Assessment

Customers find our product to fulfill IMCA requirements, easy to install, and well-fitting. Despite its smaller than three-inch inside diameter, it hasn't shown to impede power. Notably, it is practical for close-quarter installations, as validated by a drag car owner. It effectively reduces noise to a level low enough for conversations and detecting drive train noise. It stands out for its functionality and capacity to meet specific usage needs.

No trouble installing. The overall inside diameter of the muffler is much smaller than three inches. Will have to see if it affects power.

I used a pair of these on my drag car because my headers dumped right at a factory cross member. I only had a few inches to add some sort of muffler. I did it to keep my neighbors from complaining. It has worked, and you can even talk while the car is running. Also is quiet enough to hear any drive train noise.
