Gear - Superbike Slip-Ons

Put this on your pipe and smoke it!

Superbikes reside in the highest echelons of the motorcycle realm, possessing the purest racing DNA. But if you want your superbike to perform like its race-winning progenitor, it's going to need some work. Few bolt-ons will get you closer to your goal than a freer-flowing slip-on exhaust like the ones featured here.

MV Agusta Factory Exhaust
The redesigned F4 isn't available in the U.S. just yet, but MV Agusta USA has already made it known that the bike will be supported by a full line of performance parts including this stainless-steel slip-on with carbon-fiber end caps. A full-race system with pre-flashed ECU will also be available, and lightweight titanium options are expected to follow. The components will be available through dealers shortly after the F4's arrival later this summer, and although prices have not yet been set, we're hoping the Italian company's recent price restructuring extends to the goodies in the Corse catalog. Considering how marvelous the F4's stock exhaust sounds, a louder pipe is sure to be hair-raising!

Vance & Hines CS-One Slip-On
Vance & Hines started building sportbike exhausts more than 30 years ago. After a 20-year sojourn into the cruiser market, they've now returned to their roots. The new CS-One slip-on combines the legendary SoCal company's racing knowledge with sharp styling that's designed to improve the looks and performance of any sportbike, be it European or Japanese. The tetragonal stainless-steel canister is available with either a matte-black ceramic coating or mirror-polished, with a polished stainless-steel mid-pipe. The CS-One retails for $449 and is engineered to improve power and produce a more aggressive exhaust note while keeping sound levels reasonable.

Leo Vince Factory Evo II Exhaust
The Aprilia RSV4 is gorgeous-except for that gargantuan muffler. Leo Vince comes to the rescue with a range of sleek and simple exhaust solutions for this sexy Italian supermodel. Choose from slip-ons or full systems with your choice of carbon-fiber or titanium cans. Retail on the slip-ons is $699, while the full system shown here goes for $1499. Said to cut over 8 pounds, the full system also adds a few peak horsepower while boosting midrange and filling in the dip between 6000 and 7000 rpm. The cans are finished with carbon support straps and end caps, lathe-turned fittings and meticulous TIG welding throughout.

FMF Apex Slip-On
Your Neil Hodgson-replica Honda CBR1000RR just isn't complete without an FMF Apex slip-on. Handmade in the USA, the legendary Flying Machine Factory's exhausts have been battle-tested in AMA roadracing and are built for power, style and sound. Constructed from aerospace-quality stainless-steel, carbon-fiber and titanium in several combinations, the Apex's large-diameter tubing enables a higher flow rate for improved power and a deep, raspy sound. The sharp, diamond-shaped canister melds with many of today's superbikes and is designed to maximize cornering clearance. FMF's pricing is as competitive as the racers they sponsor: The Apex starts at just $359.99.

Akrapovic Evo Exhaust
Although all KTMs roll out of the Mattighofen, Austria, factory "Ready to Race," the firm's Power Parts Catalog enables owners to add even more power. The latest entry in this extensive volume is the $3670 EVO exhaust from Akrapovic. This full system is designated "For Race Use Only" and is made entirely from titanium for a massive 18-lb. weight reduction. Designed to wring every last drop of power out of your RC8R, the EVO flows spent gases so efficiently that it requires highly specialized fuel mapping, available to owners through KTM's website.

Ducati Performance Termignoni System
Ducati doesn't mess around: The stuff it sells in its performance catalog is the same kit the Italian company's World Superbike team runs. Ordering up part number 96456409B will set you back an astonishing $3566, but it'll outfit your 1198 with an impressive list of components that will boost power and make the bike thunder like the Hounds of Hell! First and foremost is the beautiful 2-1-2 Termignoni full system with massive 70mm headers and the new-style carbon-fiber silencers just like the ones works racers Noriyuki Haga and Michel Fabrizio run. Also included in the kit is a Magnetti-Marelli ECU with dedicated mapping, a carbon-fiber heel guard and a high-flow air filter. All told the kit cuts several pounds and is said to improve horsepower by as much as 8 percent.

M4 Performance Exhaust
M4's motto is, "We race to build better systems," so you know they're serious about performance. The Dallas, Texas-based company manufactures high-quality exhaust systems for all popular sportbikes, and no matter the make or model each pipe incorporates the same engineering and technology that have made M4 an industry leader. And they look as good as they perform. M4 pipes are available as slip-ons or full systems, with several canister finishes and four mounting options including Standard, High-Sport, Race and GP-style. Starting at $322, M4's slip-ons are a great value. They're said to weigh 2-3 lbs. less than the stock muffler and add nearly as much power.

Yoshimura R55-Le Slip-On
The determined minds at the Yoshimura Race Shop wasted no time when the BMW S1000RR hit the USA, releasing an array of specialty goods mere months after the Bavarian superbike became available. Along with CNC-machined case savers, a fender-eliminator kit, chassis protectors and other anodized and laser-etched bits, the YRS team is offering the R55-LE exhaust. Priced at $799, it's a genuine slip-on, plugging right into the stock collector and mounting up with just one bolt. The compact, MotoGP-style muffler is constructed from titanium with a carbon-fiber end cap, carbon heat shield and laser-etched Yoshimura logo. It's been dyno-tested and is ready to roll on your favorite back road or racetrack.
