The company’s adherence to the goal of providing products that are either completely new or providing something new in an existing product has allowed them to create phenomenal products that are trouble free.The company is determined to keep its company and its manufacturing in the United States and consequently utilizes the talent in its home state of Minnesota whenever possible.

One example of such accomplishments in the aftermarket field is the Subaru Catted Downpipe perfected to replace your OEM downpipe with its two very restrictive catalytic converters. This single high flow unit can efficaciously improve your car’s performance yet allow you to protect the environment with a catalytic converter and a high-flow 300 cell catalytic converter as an optional addition.GRIMMSPEED knows that the small things can make all the difference in your car’s performance and to that end they designed and developed the Stock Downpipe to Catback Adapter for cars like your Subaru. The company took into consideration the fact that your car’s OEM downpipe will not seal properly with a typical flat gasket because these are prone to disintegration from the elements and thus result in the inability to get a good seal. They tackled this problem and now offer you the catback adapter that will outlast your car. A comparison of GRIMMSPEED downpipes and adapters with other manufactured adapters will lead you to the conclusion that the company has recognized the problem of exhaust leaks and found the perfect solution.These are just some examples of the thought that goes into every GRIMMSPEED downpipe and adapter and the determination to “build a better mousetrap” that is cornerstone of the company’s philosophy.
