When having a Cat-Back Exhaust with the stock catalytic converter and exhaust manifold, would it make it sound better/louder with a high flow race cat and a header? The reason I ask this is because I wanna do the Magnaflow Cat-Back on my Civic, but I'm afraid that it's going to be to quiet for my liking. So I was gonna also do the DC Sports 4-1 One Piece Ceramic Header (HHC5613), and the Magnaflow Direct Fit High Flow Race Cat (22636), and an AEM Cold Air Intake (21-401C). How do you think it'll sound/perform??

 

You'll notice it. Don't worry.

watch that if you're truely unsure.

 

yea, it'll make it a little louder, and the tone will be much throatier.

remember though, louder≠better
