DynoMax Performance Exhaust has taken the guesswork out of fabricating and converting a heavy-duty truck exhaust system for use on a light truck through a new DynoMax Truck Staxx universal system. The DynoMax Truck Staxx kit enables light-truck owners to convert their existing exhaust outlet through two upright stacks located behind the passenger compartment. Available with either a 4-inch straight or angled outlet. Each DynoMax Truck Staxx kit includes staxx reducers, elbows, and hardware for a complete installation. Raincaps are available separately for straight stacks.
