4.3L Vortec aftermarket?

[Kalgorn]

I've got a 2006 Silverado 4.3 Vortec w/ a 5-speed. What kind of aftermarket is there for this thing? I'm having trouble finding stuff for it. I'm looking for little bolt-ons like a dual-exhaust catback, cold-air intake, maybe a performance chip.

 

Any help would be appreciated... thanks.

You can start with a K&N FIPK, hyperterh, and your local exhaust shop

and nitrous, lots and lots of nitrous.

How well does the Hypertech plug-in thing work? Are the results actually worth of a purchase?

best bang for the buck mods are tune (PCM for less hypertech is not good), Y-pipe and exaust, underdrive pullies, e-fans, intake

JBA makes Catback exhaust and some nice headers for an 06 4.3L. www.stsperformance.com makes underdrive pulleys. K&N makes an intake but im not sure its any better than stock, just my opinion. I have the exhaust and the headers from JBA on order, hasn't arrived yet, ill let you know how they are when the arrive.

For a tune im thinking about HPTuners. Just because i can tune both silverado's rather than buying 2 tuners for $400+. Plus you can tune MANY more settings w/ HPTuners. Just my $.02

You could always trade it in for a 5.7 or even a 6.0 SS. I wish GM would just stop putting that little 6 in the full size trucks---sorry for the sarcasm, but a 6 in a big truck just doesn't make sense to me.
