Mivv's M.HO.035.SXC STR-1 Slip-on Exhaust, Stainless Steel is made specifically for Honda CRF250R (2022-current).
Built with the best possible layout to fit the available spaces on the bike, the mivv STR-1 exhaust has been designed to ensure best performances, reliability and weight reduction.
The exhaust is made of AISI 304 stainless steel, features a 3k twill carbon cap and is equipped with a special DB-Killer optimized to reduce noise without penalizing performance.
The STR-1 exhaust has been designed so that the engine can express its best over the entire range of engine revs. The bench tests also confirmed by track tests show excellent performance at both low and high revs.
The STR-1 exhaust is equipped with latest generation sound-absorbing materials, developed by our R&D department, and complies with the increasingly stringent noise limits imposed by national and international regulations for off-road competitions. The sound-absorbing material is easily replaceable thanks to screws located in the front part of the exhaust that facilitate this operation.
The Mivv STR-1 exhaust does not require remapping and was developed without making any changes to the electronics. It is interchangeable with the stock silencer.
This product is suitable for use on track and closed courses only. It has been designed to fit a standard-equipped motorcycle as delivered by the parent company.
Note: The bench test values refer to the silencer + racing header configuration. Noise level: 114 db.
