Have a 2017 RT with the 8 speed Auto. Would like to get more power out of it. I'm not sure where to start. I don't usually mess with performance stuff but my friend got a new Mustang 5.0 and he wont shut up about it. The only thing Ive done to my car is a AEM drop in filter and a hellcat air box mod. The car has an active exhaust on it as well. Not sure if that matters or not but it sounds pretty good/loud. Help me Obi-Wans.
