  • Ok where to put a cutout before or after Cat

    Look at my mods and help me decide. With a 100 shot soon and like my headers and a 3"inch cat with a 3" sbend comeing off it where should I put the cutout for the track. Before or after the cat. Thanks

        Before if you want it loud as ****! Make sure to get an o2 sim so you won't be in open loop "limp" mode.

            I'd say after, you'd retain some backpressure with the cat still hooked up.
