I installed the high flow bassani x pipe with borla stingers. I use it as a daily driver and love the sound. The only drawback is when I have to answer the cell phone for work. Cant hear Sh!T. Even when talking to a passanger they conversation kinda fades out. Is there something you can install in the cab kinda like dynomat. That way I can keep the sound on the outside and have it quiter inside. I know ill probably get cr@p from people on the forum but oh well. There has to be a solution without having to swap my mufflers for quieter ones.
