hey thanks and dont get my mom confused with you night walking boogawuf of a mom.

It doesn't matter if you are not worried about emissions. The front housing has two wholes from the exhaust sleeve that returns up the intermediate and front irons, while the rear housing has one port going to the sleeve and that feeds to the center iron as does one of the two from the front housing. They put a tiny F and R on their housings on the top part, more toward the intake port side. Around the oil injectors.

wow now that is random :Wconfused
