FMS Performance San Bernardino Store Front

FMS San Bernardino

FMS Performance (Flow Management Solutions)

was started in May of 1974 in San Bernardino, California. FMS Performance specialized in exhaust system upgrades as a  Muffler Shop. FMS Performance exhaust system designs were quickly recognized by aftermarket distributors and were also sold around the world. As vehicles became more and more hi-tech, FMS Performance furthermore became interested in other performance enhancing products. Therefore we added other performance products. Such as  cold air intake systems, computer programming, headers, superchargers and more similar products. Team FMS Performance  is continually looking for ways to increase performance on today’s vehicles safely. Because we have the ability to manufacture, distribute, and install most of the products we sell. This gives us a better knowledge by seeing first hand how these products fit, perform and look. It also gives us the ability to see how the  customer reacts to his or her purchase.

We Install

FMS Performance takes pride in the products we offer and install. It’s like an insurance policy for your products and upgrades. If a part purchased and installed from FMS is defective within the first year, we take care of it. Ordering the new part or parts, the shipping costs, installing the new replacements and returning the defective product or products. The installation warranty on defective products is free for one year. If a part is defective, it will show up within the first year. Without this assurance you would have to remove the part, return the part to the manufacturer or the other retailer for inspection.
