Straight Pipe vs Cat-Back

well, from what I understand, the less things that are in the way of exhaust flow(for example, mufflers and cats), the more power the engine can put out. So I believe straight pipe will add more hp. And for straight pipes there's a couple options..... 1. go aftermarket and buy in my opinion, an offroad xpipe with no cats, and I don't think you can buy a catback with no mufflers so you can get a custom made catback. or 2. Just go to an exhaust shop and have them make a header back straight pipe exhaust. But having straight pipe will absolutely deafen you. My brother had an 89 5.0 with straight pipe and you couldn't think while driving. It depends on preference. So personally I'd say to go with an off road xpipe and a resonator catback or muffler'd catback. Either way it will sound mean as can be with no cats. And a side note, there are plenty of catted and muffler'd stangs out there that lay down just about the same power as a straight piped car.
