Had my Heartthrob 2.5" single exhaust installed today. It's not loud at all. It's a little quieter than the BTG 2.25" axleback I had on. My wife says you can still hear me in the parking lot
. Didn't really get to open it up a bit as I had my wife in the car all day. Did seem to pull stronger with the short bursts of accelleration I got away with her there
. I'll know better when I am in the car by myself
