The suburban drones pretty good with the 3" magnaflow. It's nice for long trips, you get in the back and the drone just lulls you to sleep like a little baby, might be nice for you, actually having a baby and all.

I can attest to this personally, I did some serious sleeping (snoring) on the way back from Mizzou.

We have 07 3/4 ton 6.0 van at work. Pretty quick without a trailer, but loaded.......
Mileage isnt bad now that we have an old man driving it. Dont know exact numbers.

I think you mean 4" exhaust. Yeah, for some reason 8.1L isn't that quiet.

'07 6.0s come with 4" factory. And a Muffler the size of Canada.

same for 5.3s. it looks like a bbq pit under there. i cut mine off in favor of a 3" 5x11x22 straight through magnaflow

Good deal grayson!

That is a good deal!...I imagine my gas mileage would suffer even more!
Probably not a good idea w/ a engine nearing 100k!

these engine are just getting broken in at 100k
