Dynatech designed these fully adjustable race mufflers to meet various sound requirements without sacrificing power. They feature a high-flow core assembly, stainless steel packing material so there's no burnout or repacking needed, and a high-temperature silver ceramic coating. The included straight and turn-down tips give you 6-position adjustment, so routing your exhaust is a breeze. You can expect a sound reduction from 4 to 8 decibels, depending upon the cone and outlet combination.
