Definitely interested in the no CEL guaranteed DP. Question, will running this downpipe with a catback without a tune hurt the car? Also would it throw a CEL if I put a catback?

Hey running it without a tune won't hurt the car. But better to tune for max gains. No CEL with a catback either.

Let me know if you'd like pricing on an Active Autowerks DP, one of the few that are guaranteed no CEL.

1) No, it should be fine. It shouldn't be enough to cause your engine to run lean unless you damaged the sensors when installing the down pipe.

2) Nope, I am running it with an HKS catback. No CEL. A CEL will be from O2 sensor which is attached to the downpipe, the catback doesn't matter.

This is the exact same setup i will be running in the next couple weeks. Just curious do you have any drone with the HKS catback?

I ran the AA DP without a tune for over a month before i tuned and didn't have any issues or CEL so as long as you install correctly and just check your work after you should be fine.

Yes, there is a soft but noticeable drone to the exhaust note in cabin.

I don't find videos and sound recordings helpful to hear drone, so as a point of comparison, it is less than the drone from my A80 (headers, 3.5" pipes, high flow cat and HKS Super Drager catback) which is quieter than many aftermarket setups.

No CEL with this setup + any catback exhaust
It also does not hurt the car, in theory, it's better for the car since it reduces restrictions and allows more air flow
