Product Details
MODIFICATION ON SOME MODEL BIKES REQUIRED. (INCLUDING OIL COOLER RELOCATION OR REMOVAL, FAIRING MODIFICATION, OR BRAKE PEDAL ADJUSTMENT) Brocks Performance Products proudly announces our 4-2-1 Sidewinder Exhaust Package. The Best of the Best Drag Race Exhaust System Available for Modern Sport Bikes. Uniquely constructed of an aerospace quality ultra-light weight stainless steel in a FOUR into TWO into ONE configuration for a smooth torque curve with a megaphone induced peak power punch! We have combined our knowledge gained over the years racing our hard launching Street Smart Systems with a purpose built Race Megaphone. A removable 2 1/4 outlet Billet Aluminum/stainless steel/fiberglass constructed baffle is included. As usual, our oversize tube design (Tapered 1 3/4 primaries meet DUAL 2 secondary pipes which merge into a velocity enhanced 2 1/4 collector) complements the ram air efficiency. BIG engines and Nitrous bikes LOVE additional pipe volume. But, the tapered head pipes prevent lost bottom end power for a hard launch and maximum acceleration, even with a stock 1000 cc engine. The entire 4-2-1 Sidewinder system weight in race trim (no baffle) is a mere 7 1/2 lbs&.baffle installed is two lbs heavier with little or no performance decrease in applications under 200 HP.
