Hi I have a 2015 ram 1500 Express 5.7 hemi. I replaced the stock muffler with a carven muffler replacement. It sounds amazing and aggressive but these past 3 days it has gotten louder. Not a bad thing lol but just curious is it normal after a month for the truck to settle with the part or what not. Temperature around the state have warned up. There's no leaks in the exhaust or muffler and nothing has come undone. Any thoughts ?
