They fit 2wd gmt900 nnbs not 4wd

 

The headers for a 99-06 will fit but the y pipe will not .... i think!

 

im ordering some coated pacesetters off speed engineering for like 360 something i believe and just going to have a custom y made to fit cause no y pipes fit the nnbs...

 

dont you just have to cut the intermediate pipe and reweld flange on nnbs?

 

Man, i would not go cheap on your headers, there is a big difference b/t the pacesetters, and say american racing headers. I know this b/c i had both. And the collectors are way better flowing, and the tubes are a little longer with better welds as well. And ory-pipe is pointless, b/c the hi-flow cats these days are almost straight through anyway. You might pick up 6 hp, but everytime you get your truck inspected you will pay extra unless you got the hook up and you would have saved money in the long run by just getting the reg y- pipe with hi-flow cats.

 

Hi, Im looking to buy lt's also. I'm thinking to buy ARH but a there a bit expensive and I also found motoblue headers. does anybody know about those headers, are they good?

 

< Running Pace Setter ceramics with ORY.....

I don't know how much has changed with the PS's, but those pipes liked my wires, so I found a solution to that.... fiberglass socks that protect the wires up to 1200 degrees Fahrenheit. I have the link if anyone needs it.
