SShorty headers I have a 2000 LS1 powered sandrail with stock manfolds from a 1999. They cleaned up better than the 2000 cast iron manifolds.
I am not running any converters. I cut off and welded up the emission tubes. I want some shorty headers that will bolt right up to my short tailpipe and mufflers.
Is the tailpipe/converter flange different with 2000 stock and shorties? Mine has a three bolt flange on both left and right sides. I want this to be a bolt on mod.
I saw on the speed channel that they gained 15HP with the shorties on a 98,

By the way.. don't believe everything you see on TV
IMO a good set of 2000 up cast iron manifolds flow about as good as aftermarket shorties.
