Actually, they have Platinum and other precious metals in them. That is why I'll get $20 each at the scrap yard for them so, $40 + shipping and they are yours.
Mine have pretty crusty looking welds on them, the one heat shield is rattling, but you'll pass emissions with them if that is what you are looking to do. Otherwise I'd penny up for a good set off somebody else.
I had bought this thinking it would solve a problem with the car but while waiting for the part to come, the car died and I had to get a fuel pump. This is brand new and never installed. $50 paypal or offer. free shipping USPS.
