Is your exhaust louder at certain revs, or is it throughout the whole rev range?  If it is louder at certain points, you can try this option, it may work for you and you may be able to keep the exhaust- Weld a second resonator in immediately behind the first one, either the same size as the piping or slightly smaller than the pipe diameter... you'll lose almost no power with doing this
Any rate, tell us what happens :)
