Thought it was going to be louder. Adds a good tone and is loud when you get on the gas. Not too loud

Very happy with price performance and of course sound.It was a bit louder than I thought it was going to be but im happy with the results. I work at a dealership so had it installed for 64 bucks.I usually get a touring but this is a performance growl! Love it!
