AC Racing Flow Exhaust system and slip on

After Building for Flow Racing Exhaust for several years AC Racing and Flow have gotten together to develop a truly unique line of high performance racing exhaust systems: the AC-FLOW line. Boasting exclusive design innovations and using materials not previously applied to off road exhaust, the AC-FLOW line delivers remarkable power increases, light weight and the durability serious racers need.

Designed, Dyno tested and manufactured at Flow’s factory in Corona, California, and track tested on some of the best known tracks in the world for over 2 years, AC-FLOW systems include a laundry list of features, many of which are exclusive to the line. For example:

• Only AC-FLOW has the exclusive “Wedge” silencer design to squeeze more sound reduction into the available space.
• Only AC-FLOW has hard anodized aluminum end caps for greater durability and good looks
• Only AC-FLOW uses a high-temp TFE O-ring on it’s MX pipes with a proprietary, Flow designed, slip adapter for an air tight yet flexible system.

And it’s not just the big components that get the custom treatment, virtually every part on the pipe is purpose designed, right down to the spring hooks and bracket weld nuts. This attention to detail and dedication to excellence results in a system that delivers top performance, light weight and durability in a unique package.

There are only two reasons to lay down your hard earned dollars for a race exhaust system: more power and less weight. The AC-FLOW line delivers big time on both counts increasing peak horsepower over stock on MX bikes by at least 1 to 1¾ HP on 250’s and 1¾ to 2¾ HP on 450’s. On Sport ATV’s, the AC-FLOW exhaust adds up to 10½ horsepower.

As for weight, AC-FLOW systems are within 10 ounces of some MX titanium systems, 16 to 20 ounces of others and save as much as 5 pounds over most stock ATV pipes. Yet an AC-FLOW pipe won’t fracture after a year of racing like many titanium systems do. And the AC-FLOW silencer won’t crack and pull apart the way carbon fiber can.

All AC-FLOW Exhaust Systems come with a USFS Approved spark arrestor and carry an innovative Crash Parts Replacement Policy that lets you replace damaged parts or even the entire system for half price in the first year, even if you crash. In addition, a proprietary EPX core is available to bring sound levels down to 96db without hurting performance.

AC-FLOW Exhaust is available for the following applications and more will be added in the months ahead:

• Even the smallest part is engineered for this exhaust to save weight and last
• Allows for more packing for less noise with clearance for caliper and oversized tires
• Uses 6063 Aluminum to save weight
• Unique Stainless Steel Slip-Adapter (MX) maintains air-tight seal while allowing enough flexibility to reduce bracket breakage
• Exclusive, High Temp TFE Teflon® O-Ring (MX) assures air-tight seal without the need for sloppy silicone – No more air leaks and backfires
• Tig welded, 304 stainless steel tubing, aircraft quality welding on Aircraft quality steel
• Stepped and Tapered Head Pipe Design
• We use .049 or .035 in specific areas of the pipe to save weight without sacrificing durability in critical areas
• Military Spec. A8625Hard Anodized Front and Rear End Caps – Up to 10 times harder than color anodizing or no anodizing – lasts longer, looks better
• CNC Wide Radius-Base Can Brackets – Radiusing reduces shear forces making it harder for cracks to form – Stronger, better, less chance of breakage
• Overall weight usually within a pound of titanium pipes but lasts much longer
• Stainless Steel 2-Bolt Flange – Designed to weigh about the same as an aluminum flange but won’t “dog-ear” so easily after tightening – Easier on/off
• USFS Approved Spark Arrestor – Takes two minutes to remove or install – You can ride where you want, when you want
• 1-year manufacturer’s Crash Parts Warranty – pay 50% of retail if you crash your pipe in first year

NOTE: All Utility ATV applications Except the Rhino-Dual come standard with EPX Sound Core
