it isn't an issue until you start making more power or/and have an old clogged up cat. no figures for you but i could hear my old cat wheezing and my 3" catback made a difference above 4500r's. the proper way to tell is to have a shop test the pressure differential across the cat. better than that tho si the fact that new aftermarket cats have build in heat shields so replacing the heat shield is not a big issue. i have a small car sound 3" i put on. a little loud but it works and is small enoughto heat up fast.
