Does anyone know is ls1 hooker lt's fit my 05 5.3 truck.

 

Hooker makes truck headers. No LS1 F-body headers will not fit. Check out Thunder Racings site for the new truck headers.

There you go!

 

I am curious to see how much they are, I have seen great results on Chevy big blocks. Hopfully they apply that to these. I like the fact that for the 6.0L they have 1 3/4 Primarys and it looks like they have 3in collectors for all of them
