So I've been searching and searching for a used high-flow catted H-pipe to buy and cannot find a single one for sale anywhere. I'm starting to think that my search will never find anything useful so I'm trying to come up with other ideas. Buying a new $400 H-pipe isn't an option right now and won't be for a long time. So instead, here's my question:
Has anyone ever looked into having two of the cats removed from the stock H-pipe? Sure, it will still be 2 1/4 tubing instead of the 2 1/2 for aftermarket, but I would think that having 'ol "test tubes" welded inplace of the two forward cats would improve exhaust flow a bit. Given the placement of those cats, is that something that could be done on the car? Or would it need to be removed to reach it? Do you think I would be able to convince a muffler shop to chop out two of the cats or are they going to have an issue with doing it? Any idea if this would give even half the Hp gain of going with a aftermarket high-flow H-pipe?
Thanks!
