Funny I didn't have that problem with southern subaru in Waldorf, MD. I have a turbo back and they didn't say anything about voiding my warranty. You can always go to Don Beyer Volvo and subaru dealership. They are in Va. just over Wilson Bridge they are pretty good about modding your car. Matter of fact they are replacing a guys up and down pipe there tomorrow but I think that is under the radar so to speak.
