What Y pipe is this?
What Y pipe is this? I pulled this off my h/c n2o ls1 with pacesetter long tubes, its 2.5" with a 3" spiral flow, I replaced it with a hooker y with a dynomax bullet and dual cutouts
Stock? Muffler shop special?

Not kooks that's all I can tell you. That may be a stock pipe I don't know cause I only had the 98 ls1's and the passenger cat was under the passenger seat but the drive's side cat was right after the manifolds. But on a side note I don't see the rear o2 opening on the driver side for after the cat so that makes me believe it is a 00-02 Stock Y-pipe but I may for sure be wrong.
