4.0 exhaust

[Mike92STX]

Can someone tell me will I have a problem with my motor not running right if I delete my muffler. The rest of my exhaust is still in pretty good shape. I guy I work with said the motor needs some back presser to run right. It's a 04 with a 4.0. I'm like most of you, I want it to make a little more noise.

Thank you for the quick response, I will probably still put an aftermarket muffler on it because like the guys on this post said it will sound better with an open muffler, maybe a cherry bomb if they still make them?

Straight piping to stock muffler will actually have decent burble and only gets loud when you rev up to 3k RPM.

By the time neighbors realize I'm loud it's just me already getting into the main road and quiets down quickly after shifting.

Why do people do dual exhaust though? Every one I've seen they don't actually have dual it's more of a split exhaust not actually each header

Does it give a different tune?
