Hello Folks, I've got a set of 355 5.2 OEM Cat's that are hollow. They also have a plug for the rear O2 bung so they could be used on a 2.7 car. These can give you the test pipe function with the looks of the OEM cat's. Or, they could be used as cores to have CAT elements installed. $250.00 to your door (lower 48 states), Paypal friends and family or add 3%. PM if interested - Thank you for looking Best Regards, Dave Image Unavailable, Please Login Image Unavailable, Please Login
Dave: Does running these cause a CEL? Is there a work around for it if it does? Any performance advantage running cat-less? Best Regards, John M
Hello John, On a 2.7 355 (95), no, these will not cause a CEL as 2.7's have no post CAT O2 sensors. On a 5.2, yes, without running extenders or such, CEL's will be thrown. Performance is less restrictive exhaust and less heat in the system. Race cars run test pipes, not CAT's. These can also be used to have them re-cored and keep the OEM look. Thank you!
FYI, these are as is, used shells that someone may re core. I'm not advocating anyone drive on the street and violate emission laws.
