Default ARH long tube - throws a code?

Good afternoon all,

I am looking at header options for my C7 Z51 and am torn between the mid-length and long tube options (both with cats) from ARH. My biggest question is will the long tube headers throw a code? It looks like they did the same type of mount on the long tubes as the mid-length headers and thus I was hoping it wouldn't code. Anyone have personal experience they can share?

Longtubes will throw a code without a tune.

Gotcha - thanks for the heads-up. I'd tune it out, but I still have a lot of warranty left. Might be a project for after the warranty is gone

The long tube headers will throw a code, Because of the wire extension you have to use on the O2 Sensors. Down Stream code. But Short headers should not. But a tune will cure it.

Porting the stock exhaust manifolds plus a secondary cat delete X-pipe won't throw any codes or require a tune.
