actually jeff, my car still had a stock chip in it. that means there was plenty of fuel and no timing, not to mention that the car was not daily driven in the few months teh cat was on. assuming the cat was damaged somehow is not an answer for disputing my claim. it was only about 3months old when removed, had stock fuel and timing tables fed to it, and was driven 2000 miles at most. it was a random tech"high flow" cat and i saw a huge gain from eliminating it. and that was after i saw no gain at all going from stock 2 1/2 to 3inch too.
the result of huge gains from going to cut outs and !cat has been proven time and time again. it takes a lot more than 5hp to see the gains i found by ditching a "high flow" cat, and it certainly shows much larger gains once you tune the engine since there is no longer the need to dump excess amounts of fuel into the engine just to protect the cat from overheating.
if anyone has lost a motor due to tuning after cat removal they messed something up pretty bad. i drove my camaro on the street, autocross, and drag strip for 3 years after i got rid of the cat and had no ill effects on the engine.
if you choose to believe a magazine test that was done to sell some parts instead of real world results, that is your mistake. look at all teh people you know who have gone !cat and every NHRA stock class car that has ditched them. if having a cat helped or didn't cost horsepower, there would be a national record holder somewhere on this planet with one, but there isn't, so that kind of settles that.
