No, you keep your Stromung muffler. You just integrate a resonator into the midpipe. Resonators are usually 14''-30" but more commonly between 18''-24." Take it to a muffler shop and they will cut out a piece of the midpipe and weld the resonator back in it's place. This should quiet the loudness and get rid of the crackles and pops. Some people use glasspacks for resonators, but whatever you get, you want it to be straight through.
