I have the AA highflow catted DP. I have had it about a year. I enjoy the sound on my stock exhaust and the improved performance. It is just enough louder than stock for my tastes.

I have just recently started get the CEL for catalyst efficiency. I will clear it and it will come back after a few days.

I do not run any burbles.

I reached out to AA and they have been great. They said just ship it back to them and they will replace the cat free of charge. I have to pay shipping to them, but they pay shipping back. They say to expect a 1 day turnaround time once it's received.

I am still pleased with my purchase as I was able to pass my obd2 emissions check a few months back.

Once I have the time to remove it and ship it back, I will report back on the experience.
