headers for 06 5.3 silverado

[Perez]

anyone know some good heads for a 06 5.3 silverado.

I think JBA has emissions compliant headers for the 5.3's

i have read a few things on those but there are allot more that are emission legal also.

Here's a tech story on JBA headers on an '07.

Are you looking for headers or heads?

Would headers void a warranty?

[chakis24]

how strict are your emissions regs?

dynomax has a nice long tube setup, they replace the cats too. its a set of long tube headers and dual cats that bolt right to the stock y pipe. i was gonna get these for my truck (but then saw theyre illegal in california emission regulated states).

dont waste your time with short tube headers (from what ive heard, ive never done any of this myself, i only know what i have seen/heard from others).

i think you might have more luck at this website with tech stuff with your truck, its another forum like this but all the posters are gm truck owners:

im looking for headers. more for racing than anything else. still trying to figure out if i want short or long and what brand.

Edelbrock also carries a better line of emission legal headers for most truck aplications.

Headers won't void the warranty. Long tube headers will get more power, but short tube headers will help too. 10-15 rwhp on a 5.3. Is that worth it for the price, maybe not. A lot of the added power from headers in a truck with a stock tune comes from the fact that the engine will run leaner. From the factory GM trucks run conservatively rich. I've seen before and after dyno runs that prove it.
