Tuning / Remap

Should I get my bike tuned?

  • Most bikes don't require remap, reflash, or tuners like Power Commander, however, we do recommend it for some European bikes like 2019-on BMW S1000RR and Ducati V4. More details are available in the description of each model.

How's the HP gain is measured? 

  • We have our own dyno and we always use the same bike, settings, fuel and temperature conditions to provide reliable results. All number are achieved without tuning the ECU

Will I get the same HP gains described?

  • You may get better results and here's why. All tests are made in Brazil where the gasoline contains 25-27% of ethanol. Ethanol has less energy efficiency than gasoline. The energy content in ethanol is 33% lower than in gasoline. This means that the engine power will be lowered when the ethanol content goes up. 

Why do I hear pops and bangs from the exhaust?

  • The engine backfire on deceleration is also caused by the too lean air/fuel ratio - A lot of people think that the backfire/popping in the exhaust is caused by too rich mixture, but it's actually the other way round. They're harmeless to the engine though. 
Is it road-legal?

All CS Racing Full exhausts feature the removal of the catalytic converter. Some slip-on models may keep both or remove the main catalytic converter while retaining the high-flow cat in the headers. As a result, these exhausts do not comply with European regulations and may not meet street legal requirements in certain countries.

FAQs

Please read our FAQs page to find out more.

Do I Need a Remap, Reflash, or Tuner for My Bike?

Most bikes do not require a remap, reflash, or an aftermarket tuner like a Power Commander. However, a proper tune can provide noticeable benefits, including improved throttle response and horsepower gains across most, if not all, RPM ranges.

What is the dB level?

Slip-on exhausts (with catalytic converter): Around 95-98 dB at mid-range RPM.

Full exhaust systems (without catalytic converter): Typically 100-102 dB on most bikes.

Ducati engines: Naturally louder, reaching up to 108 dB.

With dB killer installed: Noise is reduced by approximately 2-5 dB.

Does the exhaust include the bung for the O2 sensor?

Yes, all exhausts have the necessary holes for stock O2 sensors when required. If your bike does not have an O2 sensor, you can seal the hole with an oil pan plug, available online or at auto parts stores. Thread sizes may vary—feel free to ask us.

Is it homologated or compliant with Euro 4/5... regulations?

Although we ship to Europe daily, like all catless sport exhausts, ours are not homologated or certified for street use.

Is the dB Killer included? Is the dB Killer easy to remove?

Yes, the dB killer is included for all compatible models, and you can remove it using a simple allen key from the exhaust tip.

First of all this exhaust is handmade in Brazil so expect 6-8 weeks for delivery...but its definitely worth it. My took exactly 8 wks to get to my door from the day I placed my order. Install was perfect everything lined up exactly as it should, fit like a factory system. I immediately removed the DB killer before I even installed it so I cant speak on that tone my soul purpose in life is to wake the dead so that wasn't an option...exhaust sounds amazing. I honestly couldn't ever own a motorcycle with a full catless exhaust system, seems pointless. Order it you wont regret it...love it. My 9 yr old assistant/son and I had it installed in about 3 hrs taking our time with everything.

I've fitted plenty of exhausts on my bikes and this is without doubt the best one yet. Excellent build quality and the easiest I've ever had to fit. Pipework was accurate to the millimetre and all the fixtures and fittings scream quality. Fantastic exhaust that look and sound the part and worth every penny, HONDA 2019 CB 1000 R

Lovely product. Killer sound. It was easy to install, even with my fat fingers. I have put over a thousand miles on the exhaust and there have been no issues with needing a remap of fuel system. I don't think you are going to find a similar exhaust at the same price point.
