Anybody ever installed dual exhaust on a Tahoe 1500 (1997 , 350v8 ,
4x4)?

I'm thinking on doing that and am thinking on going with the
flowmaster setup.......I was told I need dual in and dual out , I
haven't looked underneath yet but dual in dual out does that mean I
have two catalytic converters already? If that's the case should I go
two mufflers out or just go with the single one (like I have but dual
out) I am going to shoot theses traight out the back.....opinions ,
comments?
