Race Full Exhaust System - Dr. D
Description: The unique attributes of the Dr. D’s step system allow for a more efficient intake stroke. It does this by resisting the reflective exhaust pulse during the intake/exhaust overlap. In plain language, the carefully tuned steps in the system allow for a lower net cylinder pressure, which gives a crisper throttle response from bottom to top. The key advantage of the Step System is improved low end response with substantial gain in the mid and top ranges. Dyno tests show a 3.6 horsepower increase at peak.
Features:
6160 precision formed extruded aluminum “D” shaped muffler for maximum tire clearance and centralization of the mass
6160 CNC machined aluminum mount welded directly to the muffler for strength and durability
State of the art muffler packing materials
Banded perf core for solid weld to inlet cap
Tail section S/S tube (one piece) welded directly to inlet cap to eliminate air leaks
304 SS tubing bent with accuracy using an Addison Makee high performance tube bender
Each exhaust system is welded to OEM Standards for increased product life
6160 CNC machined aluminum flange
