So the other day I got my car back from getting a rebuilt tranny. They had to fool with the exhaust alittle bit and stuff. Sounded pretty quiet back then, as I progress on driving the sound is getting louder and louder and now theres a huge drone and I dont feel like going deaf. Other than the drone it sounds awesome but im pretty sure its some leak because for one I already have an exhaust leak somewhere(ticking sound) and its so loud it drones like nooooo tomorrow. Im puttin it on ramps tomorrow, what should I check for?
