high flow catalytic converter

Well an update...

After several weeks of rainy weekends and finally getting the wheel bearings and pinion seal installed, I bought a fuel pressure regulator and got it setup. The manual say 5.5 psi and that's just about where I set it. I haven't driven yet, but just idling I can tell the fumes are much less and the exhaust even smelled better. I don't know what the psi was before and I didn't feel like cleaning up any extra fuel so I didn't hook up guage first to check. I must have been dumping a lot of fuel down the engine because I would say it smells half as much already. When I had fired the truck up back a few weeks ago and was adjusting the Carb the smell of gas and exhaust just reeked and was starting to make me sick from carbon monoxide. 30 minutes of adjusting Carb and I was really wanting some cats on it.

So thanks for the advice it really was huge help. I still may modify exhaust in future with cats but this was a huge step forward.
