Topless,
Let me see if I can scrounge up the instructions that came with the kit. If I remember they showed a nice breakdown of how the pipes were routed. At the very least, it mounts up like any conventional catback so any hpipe combo will work. Keep in mind on the little Borla mufflers the inlet and outlet pipes are on the same side of the muffler. You can always fabricate a fit ( for the flows) but it might not be cost effective. A reputable shop could tell you.
As far as losing hp I can definately tell you I didn't. SOTP isn't super scientific but when you're pretty in tune with your car you can tell if there's a gain or a loss. There was no loss. The throttle felt more open. If you're still curious, let me try to snap a few pics of different angles on the car and that might help you visualize it a bit better. I'll try to make time at work tomorrow.
BTW - not trying to dispute you MustangBelle - i've not had the car on a dyno and all cars respond differently to mods but I "felt" no loss

See ya
Brett
