My 2000 V6 manual with 251K miles is in need of one muffler on its original exhaust. I wish that I could find an OEM exhaust in good shape to replace mine with, rather than going aftermarket replacements, piece by piece (see rock auto exhaust system parts for 2000 LS). I realize that is probably not going to be found, and it's pretty tough shipping a stock cat back system as well. The prices are pretty sweet on rock auto, though, so that's probably what I will do. I just need to figure out where on the stock system we can cut and splice in aftermarket clamp style exhaust parts. I don't really like the sound of a V6 with performance exhaust, it reminds me of angry bees. Like others are saying, a healthy growl under the hood does sound nice, which I do have.
