I want to change my stock exhaust but don't want to lose any backpressure or lose MPG/HP.

I have a 2009 5.4L 4x4 and am contemplating getting a flowmaster muffler installed or spending the extra cash for a full catback gibson or magnaflow exhaust.

I can get a flowmaster delta 50 installed in place of my stock muffler for $160 out the door.

Any suggestions pro's/con's I would appreciate it.

 

First off, I'd say find a different exhaust shop. 160 for a muffler install is ridiculous, I got mine done for 80.

Bang for buck, just swap a muffler in there and call it a day. You don't gain much performance from a catback anyway.

 

no $160 is including the flowmaster delta 50 muffler and labor.

 

I know. I got a Dynomax muffler and installation for 80.

 

Oh hah.. Does that muffler sound similar to flowmasters?

 

It's a straight through design, Flows are chambered.. It's not as loud but it's a deeper/mellower tone. Then I dumped it, and it IS as loud

 

Oh nice I will have to look into that.

Does it matter if my truck has only 1k miles on it and I am already changing out stuff? I don't want to mess with any sort of break in etc.

 

Nah it won't matter. A muffler swap really doesn't change much except sound anyway.

 

K cool. Do you recommend changing anything on the intake end? Like drop in K&N filter etc?

 

I've never used an intake. I've heard they can give some good gains but to get the most out of an intake you usually need to get custom tunes, plus the tunes help keep your air/fuel ratio correct since a lot of cais change the area around the MAF sensor. I'm not sure what kind of gains the 09s are getting but on the 04-08s there are really nice gains with tunes and an intake.

 

You wouldn't by any chance have any sound clips of your exhaust would you?

 

I do but it's not on this computer. I can try to get ya one tomorrow if you want.

 

go with a dynomax bullet. check my sig for vids. its now out the back 45'd to cut down on the drone, but still exact same sound outside

 

Yea I would like that thanks!!

 

That sounds pretty damn good too! Ugh now I don't know what to choose lol.
