I've read through some of the older threads about them, but most were just that, old.

I know several people use them and are happy with them and I'm sure I would be too. The problem is I cant find them. I see them for NNBS trucks but not mine. Do any of our sponsors sell them?

Thanks,
Joey

I looked for 30 minutes and couldnt find that this morning. Are these the ones everybody is using?

I've been doing some reading and research... Looks like a lot of members prefer the Speed Engineering headers. The headers only in 1 3/4" primary size are on back order until end of April. You can still get them with the Y-pipe set OR you can still get the 1 7/8" headers only for $280.


This is the brand I will be ordering to my 99 Silverado, 5.3.

I'm looking into this as well, I need to pass visual emissions though.

The ones in that first link to eBay say they don't ship to the US. I'll dig a little deeper. I don't want to wait until April.

Ebay headers a located in Cali..... of course they ship nation wide.
As for not waiting until April.... you can buy the 1 7/8" headers from Speed Eng. now.

I may jump on those too. I see a 6.0 in my future and the bigger primaries won't hurt.
