I removed the middle suitcase and replaced them with 2 borla stype mufflers
then straight pipe out to 5" tips
sound is amazing
not really getting much drone at all with cruising....when I do get a little, I just adjust the amount of throttle
All I know is I helped a friend install the $1,400 mopar Corsa.....then afterwards he said "Damn, I wish I would have done my exhaust like yours"
