Most exhausts are taking about 35-45 days to ship out.
Most bikes do not require a remap, reflash, or an aftermarket tuner, such as 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.
While tuning is not mandatory, we do recommend it for certain European models, such as the 2019+ BMW S1000RR and Ducati V4, to maximize performance. For model-specific details, please refer to the product descriptions.
We measure HP gains using our in-house dyno, ensuring consistent and reliable results. To maintain accuracy, we always test under the same conditions—using the same bike, settings, fuel type, and temperature controls.
All performance numbers are recorded without ECU tuning, and we use gasoline containing 25-27% ethanol for testing. Using gasoline with a lower ethanol content may result in additional HP gains.
You may get better results, and here's why. All tests are made in Brazil, where the gasoline contains 25-27% ethanol. Ethanol has less energy efficiency than gasoline. The energy content of ethanol is 33% lower than that of gasoline. This means that the engine power will decrease when the ethanol content increases.
Why do I hear pops, bangs, and see flames after installing a catless aftermarket exhaust?
When you remove the catalytic converter, unburnt fuel can ignite in the exhaust, causing pops, bangs, and flames. This happens due to:
Less backpressure – A freer-flowing exhaust alters the air-fuel ratio, sometimes causing the bike to run lean.
Unburnt fuel igniting – Fuel that doesn’t burn in the engine can combust in the hot exhaust.
Deceleration pops – When engine braking occurs, leftover fuel in the exhaust ignites.
AIS (Air Injection System) – Some bikes inject extra air into the exhaust, which can increase backfire.
Lack of resonance chambers – Stock exhausts muffle noise and control fuel burn; aftermarket systems do not.
How to reduce it?
Tune the ECU to correct the air-fuel ratio.
Disable the AIS (Air Injection System) with block-off plates.
Check for exhaust leaks at the headers or mid-pipe.
Use a DB Killer or Baffle to slow exhaust flow.
Adjust deceleration fuel cut settings if your bike allows.
For some Suzuki models, we provide a block-off plate. However, certain European bikes require a remap or a servo motor eliminator, such as Servo Buddy or HealTech Exhaust Servo Motor ES Eliminator. Most Japanese bikes are less sensitive to this issue.
Yes, the dB killer is included for all compatible models, as described in the title of each listing.
Yes, you can remove it using a simple Allen key from the exhaust tip.
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.
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.
Although we ship to Europe daily, like most sports exhausts, ours are not homologated or certified for street use.
