You Said "Vroom Vroom"...

I am certainly NOT going to say that the unplugging of the actuator is harmless, I dunno. But for the life of me I cannot imagine how a little flapper valve is going to either:

A: Get the cats hot faster.
B: Significantly increase back pressure, more importantly I mean how would an increase in back pressure heat a Cat Faster?

Regardless, it's important to note that we are tinkering with OEM stuff and while it seems harmless it could have some unknown effects.
