about the power loss....wouldn't it actually help? isn't it basically the same principal as getting the headers, minus of course the smoother lines and shorter paths.
just wondering.....
There have been numerous debates on this subject....there was even a dyno that I've seen that compared a gutted pre-cat w/ sho y-pipe vs the msds headers. If my memory serves me correctly, they had similar performance.
I've got gutted pre-cats and the Sho y-pipe on my V6 LS and I can regulary hang with modified SVTs.......so I'd have to say that there is in fact a power gain.
