Dynomax Header-Back Dual Exhaust Kits

3.97 out of 5 stars 217 Customer Reviews

A dual exhaust system for the masses. Dynomax Header-Back Dual exhaust kits are designed for people who take pride in creating their own custom exhaust. They allow the installer to custom-tailor them to fit vehicles with non-OEM aftermarket headers. They're made from extra-long, 16-gauge aluminized steel for lasting durability, and the tailpipes exit out the sides. All necessary hardware and instructions are included for a complete installation. Mufflers are not included.
