So i have a 4 inch turbo back exhaust, im not sure what type, it was already installed when I got it but it has a muffler on it, but its very small. Ive also got an AFE intake, the truck has a bit of the jet plane sound at idle which I love but I was curious if doing a muffler delete would increase sound much to notice a difference or if its even worth it?? Thanks!

 

It's probably a straight through muffler design anyways, so it's probably not really knocking a lot of noise down, but I'm sure it's mellower than a straight pipe setup. It probably cuts down a ton of the raspy noise you'll get in higher RPM's.
