The InsideWinder is a state-of-the-art, 4-into-1 megaphone sidewinder exhaust system that fits inside the stock Hayabusa bodywork with no modifications required.  In fact, the system fits on dead-stock Hayabusas of all model years.  No special pans or cylinder head modifications are required.

And we can boldly state that this system makes more power than any Hayabusa street pipe on the market.

Bob Carpenter designed and built the first-ever sidewinder exhaust system in 1980 and in doing so, changed the face of NHRA Pro Stock Motorcycle drag racing to this day.  Carpenter Racing continues to innovate with the all-new InsideWinder that works for both street and track applications.

“We have led performance innovations with the Hayabusa for years so it was obvious that we should offer a new performance exhaust system,” said Bob Carpenter.  “We thought outside the box with this system and did something completely different from what is currently offered in the market.”

Current exhaust systems use a stepped header size design to increase the pipe diameter.  This design was developed as a way to fit a large-diameter pipe to the head but is not the way to make the most horsepower.  Our large-diameter, 1-3/4 inch header pipes hold a consistent size from the cylinder head to the merged 4-into-1 collector.  This allows us to get the most out of both a stock head and a head with a ported exhaust

The results of this new engineering are impressive.  “We have gained 3.5 horsepower over the next best pipe in the market on a stock head,” said Carpenter.  “Our system can also take advantage of a more aggressive exhaust port.  On a ported head we gain nine horsepower over their pipes.  Their stepped designs cannot take true advantage of a ported exhaust port like ours can.”

The InsideWinder system is constructed entirely of stainless steel and is available in polished or brushed finishes. The long megaphone has a removable 3” diameter muffler core. All fittings and mounting hardware are included.
