Barker's Made in the USA full systems and slip-ons improve peak horsepower without requiring major engine modifications, and eliminate the sudden fall-off that afflicts most stock systems near redline. This increased over-rev is particularly useful in competition. These systems have been designed to bolt in easily. This is the quickest, most cost-effective improvement you can make.
Construction: 304 Stainless Steel, tig welded with seam-reduced interior surfaces for smooth flow
Power: Reverse-cone megaphone with pulse-wave tuning technology for superior peak horsepower, enhanced over-rev and improvements throughout the rev range. Typical peak HP gain is 10-25%.
Weight: Significantly less than the stock system.
Features: Removable aluminum heat shield standard, riveted aluminum Barker's badge. Optional Quiet Core and spark arrestor inserts.
Sound level: Typically 103 dB without the silencer, and 94 dB with Quiet Core insert (with a loss of only 1.5 HP you might want to run the Quiet Core all the time!).
