I have the Bi-Modal fitted and i love it, as it does have it's own deeper sound and for me i still wanted the car to be quiet on the inside and be able to growl when needed. If you want the growl (and drone) you can pull the wiring outta fuse holder which i've done before but trade off is the drone at certain revs. Though in sports mode the down shifts sound way better


. I have put fuse back in again and i know if if i want the hoon to come out in me its 10's of work to do it, if you can get to drive 1 and you can hear difference..I personally could;nt have car without the exhaust.
