what should be a good exhaust kit?

I put on this universal muffler by Tuned products a while ago.....and now i thnk it is ridiculously loud to the point of annoying... so i put on my stock muffler again. im wondering, what is a good exhaust kit that is not too loud but still makes good flow? If anything, i might just pipe a 2 1/2 inch cat back system into a stock muffler..

saw this muffler called cherry bomb turbo II....similar to the thrush turbo or dynomax super turbo mufflers. i wonder if it is any good?
