ok, i won't use my car as the standard. i will use the hundreds of other cars, including all the thousands of cars in NHRA stock classes that had cats from the factory.
if cats didn't cost or didn't cost more power than a muffler someone would have noticed by now and the standard would be to ditch the muffler and not the cat.
my example was a cat that was bought brand new and only use for maybe 2000 miles before being deleted. at the time it was the cat on the market claiming the highest flow of any unit available. my results are a perfect example of what a cat does to performance. a brand new part that the car improved a ton after it was removed.
it is also the same result that little g, foff667, evil90ss, projectz28, and god knows how many more people we both know saw.
