So I've been suffering ever since I installed a catless downpipe .

It drones pretty bad between around 2-3k rpm especially under full boost with a deep bass tone

Is there any way to make the drone disappear as it is getting very irritating at this point.
 
Powervalve 200 cell down pipe and centre delete with anti drone...
Perfect solution and zero drone ;-)
Cheers

Put it back!

Is it legal to remove a catalytic converter?
