I have a cat. converter off of my '03 LS thats been hollowed out and added straight pipe inside. Basically it's like a test pipe that looks like the OEM cat. converter from the outside. I live in Glendale, AZ, if you're close to me I'll give this thing to the first person that comes and gets it otherwise I'm going to chuck it in the trash! It would be nice if someone at least brought me something in trade for this cat., 6 pack of Corona would be great! See pics in the "For Sale - Engine / Drivetrain / Power" forum.
