I'm looking to buy a set of Longtube Headers for my 09 GMC 5.3L before I install a cam in a couple months.
I'm thinking about going with the LPP longtubes. does anybody have experience with the LPP's on a NNBS 5.3L?

Any other manufacturers you guys would recommend?

I know this question may have been asked and I did search and didn't find what I'm looking for.

Thanks,

Ryan
