My 97 LSC still has the original exhaust system on it including all of the cats. It is still very quiet- too quiet. A baffle seems to have broken loose in one of the mufflers though which is enough justification for me to replace the mufflers. The local exhaust shop suggested I go with MagnaFlows - not sure which ones- as I am looking for a nice rumble. I have you-tubed and found a bunch or vid's of Mark's but most seem to have at least the 3rd cat removed in addition to performance mufflers. What kind of sound increase/tone can I expect just by replacing the mufflers at this point?
