2001 Sierra 3500 Dually 6.0L

Just got the truck. It has a hole in the manifold, and I was looking to get some easy and cheap bolt on power upgrades. Would like to start with the manifold, headers, exhaust. What type would you get and what else would you do. It needs more power while towing just getting up to speed.

Since this is a new to you truck, you might want to cover the bases. Like oxygen sensors, tank fuel pump, air temp sensor, air cleaner, clean the MAF, and check for a plugged cat convertor. If that convertor is partially plugged it can seem like a much smaller engine. We have a 3 inch cat-back pipe all the way back. Our 6.0 pulls like a big dog.

We have 4.10 gears too.

It really does pretty good. But Since I was replacing some things anyways, I wanted to bump the power a bit more. Wanted to get a list of the most recommended bolt ons

Cold air intakes and tuners are pretty popular. The intakes are up for debate though if they actually do a lot. I have one and really don't notice a difference. And a good custom tune is also really well received by most people in terms of getting more power. But it depends on what you consider "bolt on". Cams will get you the most bang for your buck in my opinion but that might be more work that you're wanting. And if you go higher than a .650 lift cam then you need to get new valve covers (or at least I think it's.650. It's somewhere around there). The engineers did a really good job on the exhuast system so I wouldn't bother with headers or anything like that. It flows pretty good as is.

 

Honestly the 6.0 is a beast from the factory. It'll pull a lot. If you're having trouble and need more power then there's a possibility things are just worn. Plugs and wires, plugged cats, gummed up injectors, etc. Better to check that stuff before putting money into parts you really don't need.
