The DynoMax VT muffler, an exclusive muffler engineered specifically to deliver the DynoMax’s trademark “Drone-Free Performance™,” is a straight-through, unrestricted design that is dyno-proven to support up to 2,000 CFM and 2,000 horsepower.

Each of the DynoMax systems feature complete 2.5-in. stainless steel mandrel bent piping and 3-in. outlet, buffed and polished, single wall, stainless steel, slant-cut 6-in. long tips. All of the systems include an H-pipe except the Camaro/Firebird system. Each system is configured to maximize OE pipe routing for each specific vehicle model and includes necessary hangers and other hardware plus handy, instructive installation guides for a fast and easy install.

The new systems are covered by a limited lifetime warranty and exclusive 90-day Performance and Sound Guarantee, an offer that lets enthusiasts try the system for 90 days.
