Question Y-converter question..

i have a 91 f150 with the 300 and was wondering if the y converter is actually a catalytic converter or just a 2-into-1?

If so then i already cut off the second converter, and now have the "Y" and an 18in. cherry bomb, i ran the truck straight off the "Y" and LOVED the sound and performance gains, then i put the cherry bomb back on and it quited down ALOT... so i was wondering if the "Y" made enough back-pressure to run it straight off of that, or if i need to keep the cherry bomb on...

THANX ALOT,
Jake

There is catalyst in the 'y' portion of the exhaust. As for your other questions, I'd say just experiment and see what works best.
