LS6 heads and cam

This is a discussion on LS6 heads and cam within the Internal Engine forums, part of the LSx Technical Help Section category; Some guys just tack half of a cat shell to an off road pipe. Looks like cats but no interference ...

    Some guys just tack half of a cat shell to an off road pipe. Looks like cats but no interference between the car and y pipe. Just a thought.

    I had hi-flow cats with my hookers and had no issues but I only had them on for around a month. Then it was true dual time. Now, my true duals sit in the junk yard, awaiting crushing or melting down

    NJ is strict as hell. If I were you I'd call Summit and order a set of universal Magnaflow hi-flow cats MPE-53006CA ($65 each), drive to PA and have a shop bend a set of custom pipes for your car

    $65 a piece? Damn thats great. A kooks catted-y is about $600 if i remember correctly. Thatll save me a TON. 3" pipes are easy to come by. Thanks for the idea!

    I'd still get the rear o2s tuned out, but have them inplace for the visual....sometimes you can get a Low Catlyst code with the high flows if your rear o2s aren't turned off. the emissions check will show no codes and look loke everything is intact
    nothing wrong with save a few bucks too!

    Electric cutouts are your friend.

    yeah, i want my ground clearance. How far down can the Cats be located before getting problems...IF itll cause problems. under the drivers side it needs to be located a little farther away.

    BUT...back to the LS6 stuff...would it be possible to use the stock ls6 heads with a bigger cam, and keep the car easy to drive and descent gas mileage? (even though i really dont car about MPG)
    i know the LS6 cam with ls6 heads should be about 50 rwhp from what Ive read
