T56 Magnum Conversion
Its the TTI 2.5" X-pipe system with the TTI full length step headers. I am not using catalytic converters. I would suggest NOT doing that, I think they will be too close to the floor and cook you to death. I also don't know how you could put them close enough for them to light off. It will still stink at cold start if it did before.
You won't smell like fuel unless you stand behind the car while it's warming up. This engine with the EFI and previously carb (and my previous 360 with magnum heads) ran pretty clean. If you're running the old school open chamber heads and/or a giant cam it might be a different story.
