I'm going to be deleting my ac/smog as soon as i get my o/r h pipe in. Here is my question: I see smog pump eliminator pulleys for sale all the time, is it wisest to get a free spinning pulley, or just get a shorter belt? With the ac/smog removed, is it hard to get a belt in the right pattern, and is this the reason why people offer a smog eliminator pulley? Or is the smog eliminator pulley just a useless accessory. Thanks.
