Stage 1 is the basic engine modification for modern Harley-Davidson motorcycles. EPA requires to use the sound restrictors, catalysts, lean fuel mixture - all this reduces power, increases the engine temperature and sugnisifisantly limits the max RPM.
We chose the S&S Superstreet exhaust which provides max torque with low dB sound level. This pipe is compact and fits well, especially with the stainless steel finish.
The S&S Stealth air box is a classic solution with the best performance.
The Thundermax ECU is the most compact auto tuner with wideband O2 sensors on the market. It lowers the engine temperature and increases a lot the RPM limiter, making the gears much longer and riding more fun, comfortable, faster and intense.
