Using the propane idea, the fuel is added AFTER the cats, near the tailpipes, so the cats aren't even close to the picture.


The idea sizerman is thinking of works when 1 cylinder is unplugged and the motor's reving like a bitch (rich *** exhaust path). It also works with all plugged in and the choke open wide up.

 

Too much junk,and no benefit other than fireworks.Whatever floats your boat?

 

Thats what I am saying...
