So ... I got my little 2013 prius c almsot 2 years ago and for the last year i have driven around with my muffler disconnected. Was very fun! The sound was a bit heinous. Not bad idling, silly full out. But I finally decided to put her back to rights. Honestly ... I'm sad. I had so much fun and I just want that feel again but legally + any other fun mods to give her more power or fun factor!
