Agree with the above... Comptech's are the way to go. Tip is nice but not too big.. and the sound is sweet.
They have a nice low rumble when driving. At low RPMs (2000rpm or so) they have kind of a hum. Some people like it.. others don't. Personally I don't even notice it anymore. These exhausts really finish off the car... making it look and sound like it has 260hp!
