Excessive Autosports LLC is a Automotive performance shop located in Sioux falls, SD. We have been around for 24 years. We have owned and operated a Dyno jet dyno for 21 years.

Not a day goes by in which the Excessive Autosports LLC garage isn't crammed with Supras, Nissans, Corvettes, Mustangs, Vipers and other cars, along with engines being built, turbo kits being assembled, electronics being installed and cars being dyno tuned.
