they offer both. if you go to their website you can download a pdf application chart. the single side exit has a 40 series I do belive. it is actually sounds better in my opion but I like dual out. It is a bit of a trade off.

I have the Flowmaster 80-series, and I really think that f-bodies look much sweeter with dual outs. I don't have tips on mine, but did however get the tips of the 2.5'' exit pipes mandrel bent down; mainly for bumper-clearance reasons ('91 T/A ground effects are low as heck)... but because the sound deflects off the pavement, there's more exterior resonance
...a great side-effect of the bent-tips. 80-series is the way I think you should go if you wanna' keep a traditional f-body look.
