    High Flow Cats

    I'm looking at getting a set of pacesetter long tube headers along with some high flow cats. I still haven't decided if i'm going to to a true dual 3'' or single 3''. Anyone have a sugestions on high flow cat that won't require me to cut off a limb to pay for it. Since I have to buy 2 cats, I'm look for cheap but good quality!

    I have my wishes too, but reality bites....

    High flow cats arent too expensive, Random make a set, just make friends with the muffler shop.

    In regards to 3" dual or single it all depends on your power output. If you will make 375+ at the wheel go dual, if less stay single...

    dynatech makes them to, pacesetters suck and a single to dual 3 inches is a huge ass difference, it would be more of a question of a single 3 or dual 2.5's. if you go duals, get an x pipe. a single 3 inch pipe would be alot cheaper and give you a broader power band, but lt headers x pipe duals... is there really a question, and go ahead and get ss headers, they will last u forever, those obx's are stainless steel and come with "hi flow cats" if there is such a thing and they are only 500 on ebay, go check them out
