"GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. In short, we are a small group of highly dedicated car nuts who work in Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering we started developing products for: Mitsubishi, MazdaSpeed, and Hyundai markets. We are a true garage start-up and we've been lucky enough over the years to be able to turn it into exactly the business I had dreamed....probably a lot more actually. We have a wide breadth of expertise consisting of exhaust design, gaskets, pullies, phenolic spacers, porting and polishing(services that our company was actually founded on), boost controllers, and many more." - GrimmSpeed
