just did the gutted precats last night! much easier than i expected and a noticeable butt dyno difference. although i stripped my god damn y-pipe to manifold bolt and cant tighten it so i got a wicked exhaust leak....but that will be fixed tomorrow. there was so much catalyst in there it is no wonder people do this mod! glad its finally done
thanks to todras for posting the link and whoever put together the how-to. very simple mod....saved me $600 more or less
