I'm with him.
4.8 longtubes cats and magnaflow with CAI and tune for 89
Filled up, cost $76, did the math and got 12.9 mpg, but I'm 90% city driving. Never really have gotten a change to test highway with the current setup. I know untuned I got 17 on the highway... My trucks a beast

Anyone wanna buy a truck??

 

OP how does your exhaust sound with the straight pipe in place of the muffler?

 

I'll be looking into this as well if things dont get better before I get home from this deployment. Between my Silvy and her Hoe we will be broke!

 

depressing thread. makes me think twice about going with a 6.0 swap...maybe another 4.8 and sell the damn thing.

 

mine does about 11-12mpg on the street... im use to it.. but i do have a street bike to drive around.... 30+mpg haha...

 

well both my chevys get around 12-13 in town, the 02 gets about 19 on the Hwy, and the 2008 get about 21 when i drive like a granny, the dodge dont even ask lol

 

My Avy gets 15-17 in the city, no mods. I have a corolla that I drive to work. I have to admit that I seem to be driving my truck less and less lately. AND I HATE THAT!!!!!!

 

I like the way it sounds. It's loud when you're on it, and not so much when you're cruising. Really throaty. Cheap fix too. I think it cost me 20 bucks to have them chop the stock muffler and weld in a piece of pipe.

As long as you still have cats, it really isn't loud at all. I've already decided to go with pacesetters and an ORY, so i'm going to have to put a muffler back on it soon. But, that shouldn't be an issue.

 

someone pleasefor selling my sport bike... i was getting 12mpg with a 3200 stall, i havent driven it yet with the 3800
