The Brullen mufflers are all straight through designs. The difference is the internal packing material and the length of the muffler-this is what makes one quiet and the other loud. Also, the resonated tips will be slightly quieter than the DTM or non-resoanted style. There is NO rasp with this system (WITHOUT a resonator) due to the thicker SS pipe used. You WILL NOT be disappointed with this system.
