I couldnt start my exhaust install until this coming weekend cuz it got delivered monday and when I opened the box I found a foot long piece of pipe that kinda looked like a very short test pipe. What is that? I have the dp, cat, mid pipe and canister and for the life of me i cant figure out what that is

Also, do I need an o2 sensor spacer if I have your high flow cat?? Sorry for the noob questions.

 

I think it used only when you use the stock DP and Cat. it's an extension piece.

 

The short section you are talking about is an adapter for the cat-back if it was being mated to a stock cat. If you purchased our entire turbo back system, then you will not be using this piece.

You can install the entire turbo back in the car and drive it around to see if the check engine light comes on. We have seen some cars need the spacer and some do not in order to keep the check engine light from coming on. Keep in mind that even though you have a cat on the car it might still throw the check engine light because it is a high flow cat allowing more air to pass through it than the stock cat does.

 

Helpful as always! Thanks!
