Thunderheader – Chrome 2-Into-1 Exhaust System fits ’99-’05 Dyna Models W/ Mid & Forward Controls (No O2 Ports)

The Thunderheader 2 into 1 exhaust system features a patented collector design that allows spent exhaust gasses to flow in a spiral motion through four acoustical dampening chambers. Exhaust gases flow through these chambers at high velocity and scavenge the spent exhaust from the combustion chamber bringing in a fresh charge of air/fuel mixture. The anti-reversion design on the Thunderheader Exhaust works to impede reverse flow through the system.

If you’re looking for a performance two into one system the Thunderheader has stood the test of time and has been a favorite pipe for years.
