Hi guys, I have an 05 euro 6mt with an injen cai. Finally decided on the PLM headers from jdmyard. Took the system to an exhaust shop today to get a quote on install and aftermarket cat. They were concerned about the 2nd 02 sensor on the stock cat and where it would go on the PLM header as the 2nd bung for the 02 is on the decat part of the headers. I am running the stock exhaust, anyone got advice as to where the 2nd o2 sensor should go? They told me I would possibly have to get the car retuned to stop it giving me cel codes etc. Can anyone here with PLM headers chime in and give me some advice would be appreciated. Cheers
