1. You have 2 extra cylinders

.
2. You have BORLA.
3. You have headers.
All i have is the mac cat back exhaust..
Soon: high flow cats and long tube headers
It`ll sound pretty much the same + louder
Oh and at 5k RPM when I drive.. it sounds so good !! I let my friend drive the car around the block without me in the car.. and I told him to floor it so i can hear it... it sounds awesome
