Cobra Slip on baffle removal

Any reason I shouldn't remove the baffle entirely from the slip on. I like it, I like the sound but to me the louder the better. I have a BAK intake and just installed a EJK programmer. My biggest concern is losing back pressure. I really like back pressure as it aids in stopping while down shifting. If I take the baffle out will I lose all my back pressure or a bunch of it?
