Hello MN Subaru, We are currently in the process of buttoning up our cat-back exhaust system, and are looking for a GR Sedan to test and confirm fitment. Must have stock or GrimmSpeed downpipe installed! Arrangements can be made to pick up or drop off you/your car from work or home as needed. As always, in exchange for your help, testers will be offered heavily discounted parts or giftcards. If you are interested please get in touch with me via email.
