Backed by over 40 years of exhaust experience and built in Montana, MPI delivers the sound and performance your classic Ford deserves.

Our MPI Clamp-on kits are made of quality aluminized tubing with a tough, bright finish that protects from the elements. This tubing has provided excellent results for us in Montana over the past 25 years while withstanding the extreme salt back east for many winters. Finished with our 3.5" x 10" tips to balance sound and looks, MPI kits are proudly manufactured in Montana.
