Bring on the Power with the Best Exhaust for the BMW S1000RR


Unveiled to the press in 2009, BMW initially made the S1000RR in small numbers. This limited run satisfied homologation rules, allowing the bike to compete in the World Superbike Championships. The high revving 999cc inline 4-cylinder motorcycle was a dramatic departure for the factory, having made their name with boxer twin engines.

Although success on the track was slow at first, within a year, Ayrton Badovini had won almost every single round of the 2010 Superstock Championship. Two years later, the BMW team secured a one-two finish at Donnington Park and in 2014; the Isle of Man TT witnessed their most significant victory to date.


BMW S1000RR: Triple Win at the TT 

On the 31st May 2014, TT veteran Michael Dunlop gave BMW their first win on the island for 75 years. He went on to prove that the win was no fluke; by winning the Superstock class three days later. The ultimate accolade for both rider and machine came on the 6th June when Dunlop made it a hat-trick by winning the Senior TT.

The BMW S1000RR had already proven itself as a major force on the street as well as a hit with the motorcycling press. The triple TT victories though, against the fastest production bikes in the world, cemented its status.

BMW’s single-mindedness obviously paid-off and the specification for the 199bhp bike was as impressive as its 10.2 second ¼ mile time.

BMW S1000RR: Ground Breaking Rider Aids

Apart from a host of groundbreaking electronic rider aids, engine management consisted of electronic fuel injection with ride by wire and knock sensor. While emission regulations were taken care of by a 3-way closed-loop catalytic converter that featured an interference pipe and acoustic valving.

Theoretically, with such a high performing engine as standard, not to mention highly complex emission electronics, it’s hard to imagine why anyone would want to change it.

The moment the bike went on sale, aftermarket exhaust manufacturers began the complicated task of creating something to outperform the standard offering.

Best Exhaust for the BMW S1000RR #1: Akrapovic Race Line Full System

Slovenian exhaust gurus Akrapovic need no introduction. The company has been producing high-quality exhausts since 1991, and the Race Line exhaust system made specifically for the S1000RR is no exception.

The silencer is carbon, the hanger, titanium, and the headers and middle pipes on the system come in high-quality stainless steel conical tubes. The pipes are hydroformed, which is a method of injecting high-pressure water into the tubes to form them into the required shapes.

This method allows for precision bends, without causing creases in the pipe thus eliminating interruption in the gas flow. The exact shape of the exhaust is formulated on Akrapovic’s in-house computer controlled flow benches to give greater performance throughout the rev range.

Increased power and torque say the company allows for a much smoother ride and no fuel remapping is required. Dyno runs show a slight boost in horsepower and torque, but the weight saving is impressive being half the weight of the stock item.

Best Exhaust for the BMW S1000RR #2: SC Project Slip-On Range


Located near Milan in Italy, SC Project’s state of the art factory specializes in collaborating with some of the world’s most famous motorcycle race teams.

Their in-house research and development department is responsible for creating exhausts for too many Moto GP teams, to list.  Their claim to fame in 2017 is having SC Project pipes on both Dani Pedrosa and Marc Marquez Repsol Honda race bikes.

SPC produce a series of three slip-on silencers for the S1000RR, starting with the S1. The conically shaped muffler is a titanium construction with a carbon fiber exit cone.

This version is for track only and developed for Moto GP. The use of top quality components in the construction and precision CNC machined collar mean that it is light enough and strong enough to do without a mounting hanger.

The GP M2 is a carbon fiber silencer with CNC machined exit pipe. The can is street legal and doesn’t require any tweaking to the fueling system. Everything needed to mount the silencer is included in the kit, together with CEE homologation certificate. The M2 comes with a DB Killer baffle, which can be taken out for track use.

The top of the range CR-T silencer is another track only unit that has come straight from the Kawasaki, Yamaha and Aprilia Moto GP bikes. All conical joints, bushing as well as the body of the can are of titanium, and a carbon protector, as well as a link pipe, is included.

 

Best Exhaust for the BMW S1000RR #3: Taylor Made Racing B17 Full System


TMR is a bespoke manufacturing company working out of Van Nuys, California. They specialize in making accessories for superbike race teams from composite materials and exhaust systems for select late model sports bikes.

Their S1000RR full exhaust system covers models from 2010 to present, but their latest offering for 2017, B17 full system is as beautiful as it is technically advanced.

Working closely with Simon Murton, concept designer for Matrix Revolutions movies, and S1000RR owner, Taylormade call the model, their techno-futuristic stealth exhaust.

The system consists of handmade thin wall tapered header pipes which convene in an under chassis multi-chamber muffler. Both receive a CCT (cool ceramic technology) coating to cope with the heat kicked out from the 200hp engine.

The whole system lives behind skillfully crafted carbon fiber panels, which complement the complex factory bodywork. Power is boosted over the stock system and weighs in 12lb lighter than the works exhaust.

As you would expect from a bespoke handmade exhaust system, the cost is reassuringly expensive, but around the same as the Akrapovic.


Best Exhaust for the BMW S1000RR #4: Leo Vince R Evo II Full System


Interestingly, the Leo Vince story starts in Italy in 1954, when the company made exhaust systems for two and four stroke motorcycles. There can’t be many companies who can say they’ve been in the aftermarket exhaust market for over 60 years.

Not surprisingly, with that kind of track record, they’ve learned some valuable lessons when it comes to extracting horsepower and the Factory R EVO II system is the perfect example.

Developed on the track for their SBK Factory line, the system features TIG-welded stainless steel headers. The silencer is a titanium construction outer with titanium internals and carbon end cap.

The system represents a substantial weight saving over the original and gives an increase in horsepower and torque. The bike’s original Lambda sensors are re-useable on the system.

Best Exhaust for the BMW S1000RR: New for 2017

The BMW S1000RR has been a remarkable stand out bike since its launch in 2009. It has enjoyed success in some of the world’s toughest races and received high profile industry awards on both sides of the Atlantic.

In 2017, the model received seven key updates, mostly relating to the bodywork, seat and the addition of DTC (direct traction control). The item that caused the most interest for aftermarket exhaust manufacturers, however, was the new Euro 4 compliance.

These new emission requirements affect everything from engine mapping to catalytic converters, and that means one thing, its back to the drawing board and dyno to bring you the best exhaust for the BMW S1000RR.
