P0430 Catalyst System Efficiency Below Threshold (Bank 2)

I would assume I am getting this code because of my off road pipe (no cats)


It's a Mustang GT. A Ford product. Need I say more?

You would assume correctly


2001 Dark Highland Green Bullitt
12.25@110 naturally aspirated on a bone stock 2V longblock

Under Reconstruction for RS275 Drag Radial Class
Pushrods and Powerglide Coming Soon

If it weren't for physics and law enforcement, I'd be unstoppable.

You got it. Get a tuner to turn off the rear O2's or mils to get rid of it.
