ZR2 Burnout

Finishin off a couple BFG's.
For all those that ask what exhaust it is - it's just a straight pipe after the cat. I'm now catless. I get way better mileage, but it's annoying. I'm ready for quiet.

Still won't get out of it's own way!

auto or 5 speed? and if u deleted the cats did u take them off or gut them and did ur check engine light come on i wanna know this bc i wanna do away with mine

[cowboyzr2]

@WVchevyman01 Automatic. You will get a code p0420 (Catalyst System Efficiency Below Threshold) if you delete your cat. You can get around this.. Ya just need to go to the "Help!" parts section at your local autoparts store... Get the SparkPlug Non-Foulers (P/N 42002). You need to run your 02 sensors through these to restrict the amount of gas going to them. Shoot me a personal message and I'll send ya a link on how to do it.

@WVchevyman01 sooner or later the codes always going to come up and in gm trucks when any code is thrown for a o2 sensor it puts the system into "limp mode leaving your truck running in openloop running rich getting about half the milage you are capable of, thats whats going on with mine
