Anyone using a plow setup with this truck... by learncpr

Has anyone out there investigated putting a plow on the new body duramax? Been getting some conflicting info. Looking into a crew cab but want to put a plow on the front. Probably just a 7'6" or 8'2" BOSS, but want to make sure the front end will support it and have no warranty issues with the dealer or GM. Is there a difference in the suspensions between the Classic Series(ok for the plow) and the NBS(not ok). Seems crazy to own a heavy duty pick up with an extremely powerful engine and not be able to plow snow with it. Thanks in advance.

Has anyone installed a cold air intake on the 6 liter? Is it worth the $250?
How about installing a new exhaust also?

Well depends on what you're looking for. If you have a need for increase in noise then both would increase in cab noise or to some....music.
 
If you're looking for performance or mileage increase...well, save your money.

is it ok to run a 04 5.3l without a muffler or does it really need some back pressure. Thanks for your help?

Thats what I thought. Any idea on what would happen if the truck was run for a long time with out back pressure. Thanks

Besides having no power and struggling along all day long and causing unncessary wear on the motor and drivetrain I don't see any other problems.

Tune-Up on 2000 GMC Sierra 4.3L V-6 by dhillger

I have a 2000 GMC Sierra 4.3L V-6 step-side single cab truck.
 
I am planning on doing a tune-up on my truck and was wondering what all i should do? Its got 113K miles.
 
I also want to try to beef up the engine a little. Maybe a cold air intake, headers, and exhaust. Any suggestions on what kind of exhaust will get me loudest sound but stay legal?
 
Also what else could I get to suck some more power out of that v-6?

Unless you're willing to install a supercharger by obyone

I suggest that you save your money. A cat back will give you better sounds, then again don't know how good a v6 will sound as it may not be to your liking. One thing for sure you won't get that big block sound that you're probably looking for.
 
Headers and cold intake won't do much for you either I'm afraid. However, gears might.
 
Sorry if this post isn't what you want to hear.
 
As far as tuneup replacing the plug and wires is about all it takes in that department.
