  • 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?

Yes, youmay get better results and here's why. All tests are made in Brazil where the gasoline has 25-27% of ethanol. Ethanol have less power than gasoline. 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. 

  • I have a Servo Motor Error Light on. What should I do?

We send a block off plate for some of Suzuki models, however, some European bikes require a remap or a servo motor eliminator, also known as Servo Buddy or HealTech Exhaust Servo Motor ES Eliminator. Japanese bikes are not that picky about it. 

  • Is the dB Killer included? 
Yes, for most models we included it for free, however, the dB killer is not compatible with a few models.

  • Does the exhaust include the bung for the O2 sensor?
Yes, all exhausts come with the hole(s) to fit the stock O2 sensor(s) when needed. Some bikes in specific countries may not have the O2 sensor and the hole can be close with a simple oil pan plug found online or in Auto Parts Stores. The thread of the plugs may vary. Just ask us. 

  • Is it homologated or Euro 4/5... compliant?

Even though we ship to Europe every day, like most sport exhausts, ours are not homologated or certified for street use.
