So my question is with the ARK exhaust since its a full Cat back system which means you remove the rear cat wont it cause engine light to come on? Also wont you have issues smogging the vehicle? I think theres an ait fuel sensor where will it plug in to?

 

I have the ARK exhaust installed. No CEL and was told by ARK themselves that it will pass smog.

 

i have the ARK as well, no CEL and i absolutely love it

 

For those with the ARK installed, when braking, do you feel a jolt when it downshifts? It kinda feels like back pressure that pushes the car.

 

So is there a place where you connect the air fuel sensor or does it come off?

 

I think you're talking about the sensor that is connected to the primary cats.

 

You're not removing th primary cat, just the secondary.

 

Just get the Ark Exhaust you won't regret it

Visited the corporate office awhile back...Great guys making awesome products

 

MY 2023 IS350 had the CEL come on, which also disengaged security features and lit up other lights.. Dealer says they can't turn it off unless they re-install OEM for $5K.

Did you ever get this resolved?

 

I had a CEL on for just Cut-out Valved Exhaust on Lexus RC350, they don't always come on, like after a week or the weather drops low, code P013A running Rich to Lean, Engineers says it's because the computer thinks it has exhaust leaks or dumbing too much fuels. Axle-back is fine no CEL nothing.
