Updated Cattman header for 5/5.5 gen

[RSG]

Spoke with Brian this afternoon and finally ordered the Muffler/Rear Section as my first mod.

FYI... He told me he'll be releasing an updated header for 5/5.5 gen in the next 1-2 weeks with improved design around the EGR port. Price will be set at $799.

For a 5.5 a header is a good mod. For a 5.th gen the header will not give you as much of a gain as a Y-pipe. $800. is a lot for a header too. I know it's cattman, but... On a 5th gen a header will lose some of your bottem end.
