I got an AEM CAI and I only got a muffler not a whole exhaust system. Though I did get the resonator removed.
Thanks for the reply.
I don't recall anyone mentioning the AEM CAI causing any drone.
I don't think anyone but you has removed the exhaust resonator under the passenger door.
The reason for all my questions is that I am considering removing the exhaust resonator to simplify the exhaust and perhaps add a bit of tone to the exhaust.
As I mentioned, I have removed both air intake resonators and have no drone. Our HRV has a CVT trans also.
I have tons of experience modifying air boxes and exhausts on other vehicles.
Did you swap mufflers and delete the exhaust resonator at the same time?
Do you recall what change caused the drone?
