About the Product

Brock’s Performance Products proudly announces our 4-2-1™ Sidewinder Exhaust Package for the 99-07 Hayabusa

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 StreetSmart 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 of the GSX-R1000. 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.

Ground clearance is at a maximum when using a Brock’s Performance Billet oil pan

The system is spring mounted for easy removal in race maintenance situations which also makes oil filter replacement a breeze.

Special Note: Fairing modifications are required except on the 2001/02 GSX-R1000. A cut-out template is included. The GSX-R1300 4-2-1™ Sidewinder is purpose built FULL RACE exhaust system designed for closed course competition use only. Even though we stagger our upper and lower secondary tubes for maximum right hand cornering clearance, it is still limited….as a result street use is NOT RECOMMENDED (see our Street Megaphone System)

Also note: the factory P.A.I.R. valve/pump must be removed from the front of the engine. See our PAIR removal kit

The 4-2-1™ Sidewinder system is a joint effort between Brock Davidson Enterprises and Hindle Manufacturing of Canada. This partnership combines Hindle's renowned handcrafted quality with Davidson's 20 years of sportbike drag racing experience. Davidson personally designed and hand-tuned the system specifically for the Hayabusa street bike owner who frequents the drag strip or is particularly interested in arm-straightening acceleration from a dead stop or slow roll and wants to make sure they have the fastest bike out there.

Includes:

Detailed exhaust system installation instructions

Suggested air box modification instructions (model specific-when required)

Dynojet Power Commander TRACK maps (These allow the bike to accelerate harder in the real world!) for your specific application

Dyno maps are available upon request...if impressing your buddies is important to you.
