Product details
Product information
Overview
Internally the system is open with an small offshoot path leading to the main chamber designed to bounce soundwaves back into the exhaust flow path to eliminate unwanted frequencies. The main exhaust path is a straight through 76mm (3") pipe with offset inlet and outlet. There are no harsh twists, turns, or baffles to slow exhaust flow. You'll get full uninterrupted flow for maximum power.
