how long do they last?
i was wondering how long flowmaster cat backs and catco converters last? i found one thats 2 years old and supposed to be in good shape for 80 bucks. the guy siad it has the number 4574914 stamped on the mufler,, and i can not find this number anywhere to tell me what muffler it is. he pulled it off his 85 Iroc cause he desided to make it a drag car. so is it worth the 80 bucks??

My bad! 
Thought you were talking about just the muffler. $80 for a cat and catback is a good deal

Get a CarSound Cat. It is a lot better than Catco and a little better than Random Tech. I got mine for $60.
