Hey Jason. Just installed the 304s 1-7/8". Couple of concerns.

1. The o2 extensions had two different colored clips on them. Does one color pertain to drivers/passenger side?
2. The car has been running rich and I've had a service parking/ stabitrak message on the DIC causing the car to shutoff after two startups. Third start I gave it a little gas and was fine. I didn't plan on doing a tune since it wasn't promoted that way. But do you think it would be beneficial to install the rear 02's on one edge of the high flow cat? I can weld in a bung and see if that clears up the problem.
Thanks for all your help. I don't want to drown my spark plugs.
