Thank you for your understanding.
This is a muffler made with an emphasis on performance. It exceeds normal conditions in a wide range from zero start to maximum speed. It has been completed after repeated driving tests. It is a product that you can be confident in. The sound quality is a racing sound that matches the speed and has a very punchy deep bass.
Although it is compatible with low-down vehicles, extremely low-down vehicles (more than 30 mm down, vehicles with large side cowls) may interfere with the muffler and body, so please do not purchase or install it. Please be careful. *Please be sure to check the vehicle model before ordering. Please note that we cannot accept cancellations for products that are not defective.

The construction is lightweight and compact, which improves the operability of the vehicle. In addition, the exhaust pipe is equipped with a removable inner cone as standard. You can enjoy a variety of rides by combining the inner cone and baffle. A wide range of settings are possible, from FI cars to cab cars, as well as bore-up cars.
