Yep. On mine once off high idle (cold start) the difference at idle vs Sport is there but not very obvious. Bring the revs up even slightly in that situation and it becomes more noticeable.

I just wanted to mention, It's possible to receive a CEL based on the state of the car when doing install. If it's in a full rest state, you shouldn't have an issue. There might be a situation where when the connector was pulled it caused a discharge or low voltage reading in a sensor (thus causing the fault). These faults can be cleared by a diagnostic tool or through a few cycles/driving. This might not be the case for all faults but wanted to mention that one specifically.

I've experienced CEL if I shut the car down with the valves open. If I close them before shut down no CEL. Power cycle the car if you get a CEL and it goes away.

By power cycling the car is that just simply turning it on and off a few times?

Yes, I just turn it off and the warning is gone on re-start. Over months of use it has happened twice and in both cases I was playing with the remote opening and closing the valves right before shut down.

I left mine on for my 1 year free oil change. But ….they would hear/see the titanium catback exhaust system anyway. Doubt it would ever be an issue considering how the Cargraphic works.

My dealer was going to install mine for me before I decided to do it so, obviously, I’ll leave it on for service. What’s more, they sell and install exhaust systems. Going with a Tubi from them in a few months.
