Headers for 06 Silverado

[2001Silverado2500HD]

I have a friend that just bought an 06 1/2 ton hes lookin to buy headers for it and an exaust system. Any suggestions on headers? How much HP is usually gained adding headers on these trucks? Thanks.

If you live in a state which permits it get long tube headers. They should give a good low end gain. Probably 20-35hp/tq or so. In Ca they are illegal for emmissions so i went for shortys, only a 10hp gain or so.

I can't comment on the gains as I have never had my truck dyno'd. I did recently install the Dynatech Supermaxx headers and cats on my truck. As for exhause it has the Corsa cat-back system with dual side exit. The sound to me is excellent and the take off power has definitely went up.

 

Have a great day.

Hey dude i would defenitly but the Dynamaxx supermaxx headers, there long tube w/high flow cats, and a powder coated design, i have them myself and honestly its the best thing i bought. I wanted headers but didnt want to have to cut and modify anything like you would with every other headers. Gm acctualy gave them best new product reward and i belive won best install as well. they will put you back about $1400 but well worth it.

 

I have a programer, corsa cat-back , The dynamax supermaxx, air intake, just some simple bolt ons. and the dyno says a stock 5.3 puts 241.0 hp on the pavement at rear wheels my truck puts out 274.3 at the rear wheels so im happy

but shooting for 300 ...

Dump the programmer and run to a dyno tuner or at least do a PCM swap with Wester's or similar. The Dyno tune is your best bet as then your specific truck will be dialed in perfectly.

 

I am making 304.3 HP and 329.9 Torque at the Rear Wheels and if i had those LT headers i'd be doing much better. I only have Intake, shorties and Borla cat back but my engine is the L33 HO and my compression ratio is slightly higher than yours.

I think that with a good tuning you will get that 300HP!!
