bebop40 said he didn't like the sound , so it wouldn't cost anything to turn them around . I bought a set this year they was not marked inlet and outlet . And yes mine sound just like I remember 60 years ago ....I've got to get used to every time I put something on this forum somebody always wants to beat me up..
So I think I'll keep my opinion and what little knowledge I have to myself .... and just read ....
