There are quite a few ways to skin this cat. I usually recommend starting out by identifying local resources by asking about local cars with similar configurations, specs and sound constraints. PCA is usually a great resource for that. In most areas, there are some commonly used approaches.

Quiet Horsepower is right near my house. The proprietor, Pete, is a a really, really good guy with tons of experience in many forms of racing. He has done some fab work for me through the years. First rate in all ways. We have been extremely fortunate to have him as a resource in the racing community. This includes pro teams.

Tangerine Racing is a distributor of some of the Quiet Horsepower products.

The Phase 9 muffler was co-designed by the father of Jan Beekius, who you can see on TV as a race reporter. Jerry Woods is a co-designer as well as Pete.

The design works very well and has been implemented and tested in a wide variety of configurations and applications. Note that it the mufflers can be made in several different sizes, and some system designs include the rear chamber while others do not.

Quiet Horsepower is an excellent global resource, and you cannot go wrong having Pete create a system that meets your needs.
