I have heard a few people say that FlowMaster's have issues... how bad can the issue be?? I mean, like are we talking about big HP loss?? Because I know people that have them & love them... no issues. Anything is better than the Hooker ones I had... those were the worst mufflers ever. Bowhay is putting them on a SBC 1983 Chevy pickup with glasspacks... you really think a set of FlowMasters are going to dissapoint him?? Come on, I had some on a Chevelle & they sounded awesome... sold the car w/ them on it & like one of the past posts said, they really don't wear out fast. They have no glass in them, sound great, aren't that expensive... what is the issue? Scooter
