I know a few were asking about a video with OBX headers. Here are mine with Borla Atak CB. Only brought it up to 4K.....didn't want to piss off the neighbors.
I just went to the track this weekend. They made me go back to tech to have my car inspected after my second run. They thought my car was too loud and had no mufflers and/or cut outs. Guy looked under my car, then went on the radio, "he has mufflers and no cut outs....". Response, "really? Well, let him run...."
