Alloy Race Exhaust System - Dr. D
Description:
Full Exhaust System with Race Silencer; Race Silencer cannot be retrofitted with spark arrestor
The unique attributes of the DR. D's Step System is that it allows for a more efficient intake stroke by resisting the reflective exhaust pulse during the intake/exhaust overlap
In plain language, the carefully turned 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 arch at low end with substantial gain in the mid and top ranges
Dyno tests show a 3.6 horsepower increase at peak
Manufactured from high-quality, 304-series stainless steel
Each step in the exhaust pipe is achieved via a precision machined ring that not only adds to the performance, but gives the DR. D pipe a distinctive look
The complete system is purged and welded in one of the nation's best manufacturing facilities
The muffler is constructed out of 6063 aluminum to lower the overall weight of the system and provide an aggressive, but pleasant, exhaust note
