***ATTENTION! To avoid the "error" light, these bikes require either a remap or a servo motor eliminator, also known as Servo Buddy or HealTech Exhaust Servo Motor ES Eliminator (ESE-D03V3)*** UpMap is one of the tuners that will solve the problem. All of them can be found online.
Important Note: 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.

FAQ’s
Find more detailed answers to these questions at this link: CS Racing FAQ.
Exhaust Performance & Installation
- Do I need a remap, reflash, or tuner?
Most bikes don’t require tuning, but it can improve performance. Some European models (e.g., BMW S1000RR, Ducati V4) benefit from it. Check product descriptions for details. - How is HP gain measured?
We use a dyno under controlled conditions. Tests are done without ECU tuning using gasoline with 25-27% ethanol. Lower ethanol fuel may increase HP. - Will I get the same HP gains?
Likely better. Brazil’s fuel has 25-27% ethanol, which reduces power compared to lower-ethanol gasoline. - Why do I hear pops, bangs, and see flames?
Removing the catalytic converter allows unburnt fuel to ignite. Causes include reduced backpressure, air-fuel ratio changes, and the AIS system. - How to reduce it?
Tune the ECU
Disable AIS (Air Injection System)
Check for exhaust leaks
Use a DB Killer or Baffle - Will the exhaust trigger a servo motor error?
Some European bikes need a remap or a servo eliminator (e.g., Healtech). Most Japanese bikes aren’t affected. - Is a dB Killer included?
Yes, for all compatible models. - Is the dB Killer removable?
Yes, using an Allen key. - What is the dB level?
Slip-ons (with cat): ~95-98 dB
Full systems (without cat): ~100-102 dB
Ducati engines: Up to 108 dB
dB Killer reduces noise by ~2 dB - Does the exhaust include an O2 sensor bung?
Yes, for stock sensors. If your bike lacks an O2 sensor, seal the hole with an oil pan plug. - Is it Euro 4/5 compliant?
No, our sport exhausts are not street-certified in Europe.
Ordering & Shipping
- How long is delivery?
Orders take 30-45 days. Once ready, DHL Express delivers in 5-12 days. - When will my tracking number be available?
It’s generated when the label is created but becomes trackable after reaching DHL’s main hub. - Why isn't my tracking updating?

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.
Customer Reviews
Fitted the CS Racing exhaust to my streetfighter. Used the OFT tuning stage 2 map system. The exhaust is good quality and keeps the original look. Delivery took a few weeks but this was expected as it was coming from Brazil I believe. Very easy to fit and everything lined up really well. I’ve no complaints.
Great quality, great sound, and great looks!! I would definitely recommend this exhaust to anyone who asks!! I couldn't be happier with it, can't beat it for the price!
The exhaust was very easy to install. Fitment was perfect and it sounds amazing. The best part though I’m not sure if it’s just my bike..but the cold start hesitation went away after installing the exhaust. It starts at 1st try!!!!
The exhaust fits perfectly! Nice loud and deep tone! Best bang for the buck for sure!
Exhaust packed sufficiently, arrived with no defects.
I fitted the exhaust myself, (OEM was a PITA to get off).
Installation was a breeze and fitment top notch, not all bracket holes fit right away, but they were only the one fitted on brackets that could be bent to sit right. Not a problem in my opinion.
First start had me in shock & awe, sounds monstrous!!!
DB killers are nicely in their wrapping and in the shipping box where they belong :)
Only gripe is not a complaint towards CS, but you WILL need a re-flash to get the most out of the exhaust. I still dont know which to choose (UpMap/SLR/Brentune/Woolich?) as this brand/model has not been out long and not as popular (yet) as other main brands (expensive & do need the re-flash also), but from a price/quality standpoint, I could not be happier!!
Now to persuade CS (and their users) to develop a map for this combo and we should be golden!!
