put a catalytic converter on. rb's in general run pretty damn rich and removing the cat isnt gonna help remove those fumes at all.

get a FPR, and a gauge, set it to 43 psi vac off, and call it a day.. this speaking if you have installed a walbro, or higher grade fuel pump.. RB's run rich naturally, and if you dont have a cat, your going to get some fumes.. just stay moving and you dont even notice them
