So, my MTC cans sound great, but with baffles in, there is an annoying noise, as gasses are forced through the gap around the baffle and the end of the can, akin to a very loud reed instrument. Baffles out & the cans sound AWESOME!!! There's no weird secondary noise....
So: leave them out & risk angry plod/neighbours, or put them in & risk strange noises?? I think I have a dark hooligan side & I should seek professional advice.....
