TRD Exhaust instructions 2014 +

Can any one tell me what they are referring to in the instructions at the point of bolting the muffler to the catalytic convertor flanges it has 2 side bars labeled PPO and DIO. one you purchase the gaskets and one you don't. So what does PPO and DIO stand for. Thank you

 

Post Production Option (PPO) by Toyota or as a Dealer Installed Option (DIO) by a Toyota dealer.

 

This guy ^^^^

Hey Jim did you ever install that little bolt light? I still need to do my other one in the lower center dash / cupholder area. I've been lazy with the cold weather lately

 

Thank you, so I need to purchase the convertor pipe gasket kit also when I buy my exhaust

 

I've been busy/lazy also...lol. Not yet.
Thinking of either glove box or center console. If I do center console I'm going to have to wait because I want to get the Toyota console safe.
