I had a set of Pacesetter shorties on my old LT1 and you couldnt even look at them crossed eyed to see the flanges straight before bolting them on the heads.

Now I have an '00 SS w/23k, 6spd, and want to know if the Long Tubes by them are any good, power gains from anyone that put them on a stock SS LS1 before any other mods and their thoughts about them.
