a buddy of mine just switched from a off-road x-pipe back to one with cats, and is going to give me his old one. its a bassani. I plan on taking off the air pump now that i will have no cats. my question is do i need to get the delete kit or just buy a smalled belt and route it diffrently. It just seems smater to get rid of the pully all together. if i can do with out the pulley, does anyone know what size belt i would need.
