custom exhausts?

sorry if this has been covered, but i have a 2010 SDR with akra race cans, and i am still wanting more noise, does anyone know the loudest off the shelf exhaust for the SDR or a good custom exhaust place, in the uk? preferably east anglia or the midlands? cheers

My old Leos were louder than akras. I've heard he mivvs are very loud.....but TwistedJesters cans are pretty brutal....he has struggled with noise tests on track with his baffles IN!!!!!


I think the HP cans are loud too....but are shit with baffles in and are not cheap either...
