Brocks 4-2-1 Sidewinder Exhaust for Suzuki 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! Brock’s has combined their knowledge gained over the years racing their hard launching StreetSmart Systems with a purpose built Race Megaphone. Their 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 of today's big cc sportbikes. 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. A removable 2-1/4 outlet billet aluminum/stainless steel/fiberglass constructed baffle is included.

There is no reduced right hand cornering clearance or rear brake lever to pipe clearance issues. NO fairing modifications are required and the stock oil cooler and lines remain intact. The Street Megaphone System has a more aggressive sound than Brock’s normal street exhaust, but is still acceptable for street use with the baffle installed. By removing the billet aluminum baffle, the user can unleash a race-only sound which mimics the booming tone of an NHRA Prostock machine! The front section (from the engine to the Muffler) is constructed of an aerospace quality ultra-light stainless steel. The Street Megaphone package comes with a Race Megaphone with REMOVABLE billet aluminum baffle. The total system weight is just over 8lbs. Not just an off-the-shelf pipe, these systems are complete performance upgrade packages specifically designed for “serious stock” and large cc or heavily modified engines. The larger and more powerful your engine is the better this system functions! But stock engines love this system also. Included are specially-designed lightweight stainless steel header pipes joining to a full race megaphone, complete instructions detailing horsepower-freeing air box modifications which retain the stock air filter for maximum engine longevity, pipe installation instructions and a floppy disk containing maps for use in conjunction with the Dynojet Power Commander for your year machine.

These exhaust systems scream style and performance in true hot-rod tradition. An economical pipe aimed at the weekend racer looking for affordable performance.
