I am LOVING the sound of my new exhaust!!! Kooks 1 7/8" headers with hi-flo cats and Borla S Catback!!! It is pretty quiet at idle, but when you hit the gas it has a nice authoritative, mean growl!! Took it for a spin after install yesterday and I could definitely feel the increase in horsepower! Here is a short video of it...the video doesn't really do it justice...but toward the end of the video you can really see the torque!
