good looking rig, mj. i have been a dodge truck guy since '72, but after driving my wife's tahoe (02) with the 5.3, my next work truck will be a chevy/gmc. she was getting the same mileage your getting, but my mech suggested we switch to mobil 1 syn oil, i thought it was bs. we took it on vacation this summer pulling a trailer with gear & 2 kayaks and got an honest 20 mpg highway, 17 in town. i put it in my work truck and went from 10.5 to 12.5.
 
Thanks!!
I will have to give it a try, and see what happens??
I got crap from a guy the other day cause I have been doing Chevy since the 80's, and change the oil every 3000 miles. I am pretty anul about it also!! I use Castro oil as I had a 89 Blazer that burned some oil, and my guy back then stated I had less then 100,000 on it that there was no way I was burning that much, said your returns are blocked. Use castro for a few changes, and if it doesn't get better you will have to pull the covers, and clean it. I did 3 oil changes, and no more oil burning!! He was right, I kept that thing to almost 200K before I sold it.
So I am a firm believer, that oil changes, and stuff are the single best thing you can do for your motor!!

The only thing about the Chevy's to me are the brakes, they never feel strong enough, but they work. I have just 45,000 on this truck, but when they are due I am going to switch the rotors to drilled and slotted ones.

But I love the truck! With my boat on there you hardly even know its there.

Very solid rig indeed!!! As for the brakes, Im comin from a Ford so I agree but at the same time I wouldnt wish the Brake pads Ford uses on my worst enemy. I should have named my 07' Ford "Dusty". It was the worst I have ever seen with any vehicle and I like to think Im pretty gentle with braking.......
 
I have been GM since 1988. Couldn't agree more with the brake feel on the gas pick-ups and such MJ. My 1989 GMC Sierra had a very soft pedal. It got worked on. Luckily, the hydroboost brakes on the diesel trucks makes the brakes feel just right. When I switch from the diesel to the Tahoe it takes some adjusting.
 
Hydroboost is great. Until your power steering pump goes out. You have good brakes until you reach a certain point on the pedal. Then it goes to the floor and you have nothing. Its happened twice to me. Once on the road and the other time offroad. Dont ask about the result of the offroad brake failure....
 
My brother had that issue when the power steering went out, he was Joe what has happened?? I told him, and he said what does one have to do with the other? I said thats the way they do it.
 
Thats GM for you. If you cant steer around what you are about to hit you might as well not need brakes! Wait a minute, if you cant dodge it, RAM IT!?!?!? Dam we are driving dodge!
 
Well since we are on the topic, I need exhaust too! Any suggestions what I should go with or stay away from? Im thinkin 4" straight pipes out the back but Im scratchin my head pre-bumper......
 
If you can afford it, go with Banks. If I had a Duramax that would be my choice. I have a HeartThrob on my 6.5 and it fit well, but I wonder how a different muffler would sound. If you are on a budget, just order the downpipe aka head pipe and worry about the rest later. Just let it dump out under the cab.
 
if this is a diesel go with diamond eye..... all over ebay, dirt cheap, top notch quality... I've had it on my powerstroke for 5 years and not a speck of rust on it

If this is a gas engine, 4" is silly. Personally, while I've had some really loud vehicles in the past I've come to fee that it is selfish to force the whole world to listen to my loud exhaust and I don't do it any more.... I even had a 4" from the turbo back straight pipe set up on the powerstroke for a while but I bought a $170 high flow but quiet muffler for it.
 
A diesel running straight pipes sounds a hell of a lot better than these ricers running around. And a gazillion times better than having to listen to overbassed rap (makes me miss when my injection pump was loose and overfueling). The only real drawback to no muffler is the drone at highway speeds.

Also the way I feel, unless the whole world pays my tag registration, insurance, and fuel to hell with them. I am respectful with how loud my truck is. I deliver pizza sometimes with it. I go into high end subdivisions at eleven sometimes midnight. I am not trying to argue but your vehicle is your vehicle. Disregard for others is one thing, but just because the guy in the prius next to you does not like your exhaust does not mean you bow down to him. Besides your straight pipe diesel is less harmful to the environment than his prius.

yeah, I couldn't care less about the guy next to me in a prius....It's when my neighbors would call me and ask if it was me that drove by and woke them up at 11:15 when they had to get up at 4 am that got my attention.... My truck had absolutely no drone on the highway... I couldn't hear the exhaust in the cab at all unless the window was down and I passed a building or something to echo the sound back at me. I had not realized just how loud it was and how many people I was disturbing.
 
Okay maybe my post was misleading......Im not changin the headers or anything in front of the muffler. I was more looking to see if you guys rec'd Borla, Flowmaster, etc.....then having the pipes come straight out the back of the truck instead of to the side:haha:. Does that help?

Pipes straight out the back does help some with the drone VS out the sides. The stock exhaust is 3.5" out the back, personally I would split it off after the muffler and go out the back with dual 2 1/4" or 2 1/2" pipes if you want duals or a single 3.5" for a single as it is MORE than big enough to flow whatever a 6.0 will need(GM used the same exhaust for the 6.0, 8.1, and DURAMAX in the early years, just a different muffler for the DURAMAX). As for which muffler, I becam,e a fan of MAGNAFLOWS. They have a real deep bassy tone to them without the cackle that alot of them get, and they don't drone as bad as some others do. FLOWMASTER will always have that beer can rasp to them which is fine if you like it, but I personally don't care for it anymore. Also there is a new company out callled JONES FULL BOAR that is making knock-off copies of all the big name mufflers for about 1/3rd the cost. I just bought a set of MAGNAFLOW knock-offs from performance curve for less than half of what 1 magnaflow would have cost.
 
the muffler on my powerstroke is a donaldson... I have 4" mandrel bent exhaust from the turbo back... the truck is barely louder than stock with a great performance tone and the muffler I got flows 99% of what a straight pipe flows which is about 250% of what the stock exhaust flows... it was a bit pricey but well worth it.... It's not loud enough to piss of my neighbors but people tell me all the time that it sounds really mean.

as for duals straight out the back, I've always heard that refered to as sweethearts.... Personally I wouldn't waste any money on big names... NONE of them will do anything for performance. just go to a local muffler shop. Have them whack off the offending side exit tail pipes and bend up some that exit where you want.

As for a muffler... you have to decide what you want it to sound like.... loud quiet mellow or rowdy.... heck I dunno, maybe you want a thrush glass pack for that badah badah badah coolguy rumble :D
 
Its gas......

I would like it to sound low and throaty of course. Im not really one for the poppy sound......

Not tryin to get that screamin sound I would just like like it a tad lower and a touch louder than what it came with.

MAGNAFLOW or a JONES FULL BOAR MF series muffler would be my suggestion. There the same muffler basically, but theJONES costs 1/3rd what the MAGNAFLOW does. See if you can find a muffler shop that does dual exhaust as dual 2 1/4" pipes will be plenty out the back as you already have 3 1/2" coming back from the engine now.
