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.

that cat provides plenty of restriction....

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?

I got my exhaust finished but, I put a turn down tip on it and the exhaust twists, so the tip hits the plastic fender. I thought it was twisting because I wasn't getting the clamps tight enough. I just figured out today that it's the setup behind the catalytic converter with the half donut and the 2 bolts with springs on them. Does anyone have a better solution to hold that joint tighter?

If it's twisting there... it's also twisting in the muffler/hanger i would presume.

Maybe try tightening the hanger clamp...

Uncle Gump, I tried that first, I even used an air impact to tighten it because the inlet on the muffler is a little larger than the pipe. When it didn't seem like anything I was trying was working I laid on the ground and moved the whole exhaust system up to the catalytic converter. I tried tightening the bolts with the springs on, but it didn't make a difference. I was afraid of tightening the bolts to much because of the tabs on the nuts that keep them from turning. I was wondering if there is a different donut that would work better?
