    Hello,

    I just did a backbox chop on my Megane 265. I like the sound, but there is a really bad drone when coasting between 3-3,5k rpm. Is this a common 'problem', and something you just have to deal with when doing a backbox chop?

    Would like to hear from others running with a backbox chop.

    Thanks in advance
     
  2. You'd have been better with a mid box chop
     
  3. yep...mid box for anti-drone

    So the drone is just something that comes with the backbox chop? Nothing you can do about it?
     
  5. Yeah, put it back in and chop the mid box instead :tearsofjoy:
     
  6. delete both, if still got factory CAT and depending what using vehicle for the factory CAT is pretty good at supressing sound on its own
