If you are near Fresno there is a place called Western Muffler. They make the Xtreme Flow sieres of mufflers (like Flowmaster). They have a lifetime warranty and dont make a yota too loud (they can if you want). They sell high flow cats as well. I have had thier mufflers on a stock 22RE and a 3.0 V6 with downey headers and the high flow cat. I like them and they really made a difference. Once I have the cash I will have them do a cat and muffler on my 88 V64Runner. He quoted me about $240 for the high flow cat and muffler installed.
www.xtremeflow.com you can order the stuff online for pretty good prices, call and you may get a better deal.
