Best way to make Catback exhaust system a little louder

Replace your muffler with something small, like a dyno max bullet, glasspack, magnapack, cherrybomb extreme... Etc

Or just take the muffler off.. Straight pipes from cat back.

Or dump the exhaust right after the cats.

Bigger pipe and a 3inch in and out cherry bomb single chamber extreme muffler sounds amazing

I agree with the 3" exhaust that is what I have but I don't know about the cherry bomb muffler. I did shorty headers to 3" y pipe is High flow magna flow cats to a single high flow summit muffler. It is a nice low deep tone (not very loud but it is noticeable) at ideal but it gets load when you get on it. My wife loves it. I can't really sneak away from work though everyone knows when I start it up to leave.

Same with the setup I listed
