if you have emissions get the hooker 2151 long tube's uncoated and have a good shop coat them, and also move the o2 bung to the collector. If no emissions then the 2149 uncoated, etc.
is ther any "real" difference performance wise between 1 5/8 and 1 3/4?
Actually we went from 1 3/4 to 1 5/8 for a bit better low end since the L-98 has never been a high revving motor the low end seemed to be a better option. We had the hedman's matched to the heads and coated by swain and they have been great. Hold up good too we have a few cones melted to the bottom of ours!

I'm interested in hearing your opinion on them. They look like good bang for the buck.
I will post pics of them as well as the parts, and follow the installation, i will post as i go... truely excited about them ..... they should do well with the hi-flow cat and magna-flow exhaust system...

except that the 2151 are without the smog piping, and the 2149 is WITH the smog piping.

coating the headers keeps the "heat" inside the header for better exhaust flow and to keep the underhood temps low. My original hooker coatings lasted about 1 year of driving before they began to flake and corode. A supra friend of mine had a set of headers for his supra coated by a local shop called loko coating and they lasted for about 3 or 4 years of 12 month chicago driving w/o any problems. My headers have been coated inside and out by loko coating and the emission fittings removed along with o2 bungs weleded in the collector.
