There is another sound mode is available. This has much louder, full body sound, it’s louder than the legal limit, the control valve is not included in the approval, use it on your own responsibility. The passing by test result is more than 105dB.
The exhaust is made of stainless steel, with no any surface treatment. It’s mirror polished, doesn’t get matt. Or you can choose the matt black colour one.
Our exhausts are prefect replacement of the stock Harley-Davidson exhaust, slip-ons. Our exhausts fit on the stock Harley-Davidson manifolds only.
The exhaust tips are included in the price, you can choose according to your taste, choose the one you like when ordering.
Every engine is different, so we recommend that you have your engine calibrated after replacing the exhaust. We recommend an expert power bench set-up. Incorrect configuration, which includes incorrect adjustment, can cause excessive heating of components, which can damage the exhaust. Non-configured or misconfigured engines are not covered under warranty.
