D&D EXHAUST QUESTION OF THE WEEK-- Q: What is your best performing D&D pipe?

A: The 2 into 1 performs best due to the scavenging effect of our hand ported and polished merge collector. This serves the same function as a crossover pipe only without disturbing the flow. Fat Cats work best with stock and slightly modified engines while Boarzilla pipes are configured for big bore and highly modified applications.

Completing the burnout is an Old School Bobber built by Hardbikes. This bike runs the D&D Performance Enterprises high-performance exhaust system on a 96 inch S&S Engine with IST ignition.
