Utilizing an internal chamber/collector allows this muffler to act as both a resonator and a collector! These are great where space is an issue or noise is a real problem. These stainless resonators are one of the most effective mid mufflers available on the NZ market.
We have sold so many of these recently to keep noise levels down at race tracks around the country we thought it was time to launch them as a stand-alone product!
Because of the large body size these resonators carry a lot of packing material, reducing noise levels further.
