    Catted Y-pipe to fit manifolds/ shortys?

    i have a 2000 trans am WS6 with factory exhaust and a SLP LM1 catback. i am purchasing a set of edelbrock emissions legal shorty headers, and i understand these bolt up to my stock y pipe. does anyone have or know where i can get a catted y pipe that bolts up to these shortys / stock manifolds and require no cutting / welding to fit? i do not want to run longtubes. any info on a catted Y would be greatly appreciated.

    Check the same manufacturer that you go the headers from. If not, any factory replacement y-pipe with cats should work.

    So you want an aftermarket y-pipe with cats that bolts up to your Edelbrock shortys? Is that correct?
    IMO, you will not feel a difference with shorty headers.

    I was looking into shorty headers also, but wasn't sure if it would really make much difference in power.

    If you definately don't want longtubes, then mids over shorties no question.

    Use the stock Y pipe/cats. Don't think you'll see any gains with aftermarket.
