How bad is your cabin cat back drone?
 

Mine is pretty loud with the Magnaflow cat back. Thinking about laying down some dynamat to keep the drone out.

Pretty bad at 60, so I fitted noisier tires to drown it out.







Laying down pounds and pounds of dynamat will probably be enough to cancel out the 0.5hp gained by fitting a drony catback :dunno:

Have you tried installing a silencer or maybe an extra glasspack?

Very little drone on the CNT cat back I have.

My drone isn't too bad on the TurboXS single with no cat. But it's probably because all the road noise over powers it.

I had some drone with my Injen CBE, but after getting test pipes it really diminished.

turn up the tunes that will get rid of the drone :yeah:
