I dunno if its just me, but I thought putting on a catback gave around 8hp increase?
Adding a "second pipe and muffler" to a single exhaust system (i.e. quasi-dual) is just for looks.
The second pipe and muffler do nothing but add weight and looks. (i.e. balanced rear view in the SVT's case)
True, but replacing that horrid resonator with a proper straight through design will help a little on the top end, as will a modded Y. Along with a good intake system upgrade, you'll get the punch of a few extra HP.
I've put an SVT exhaust on 2 V-6 Contiques now, & replaced the res with a Magnaflow 5x8 on both of them. More free revving up top for sure. HP increase? - likely yes, but not measured. I do mine for the sound & the looks... 
Must be that jumbly-wumbly thing happening again.
