The premium version of the Arrow Thunder exhaust silencer comes with carbon end cap, this one here instead with steel end cap. But thanks to its length it still looks good on any Yamaha YZF-R-125. The sound is about the same on all Arrow models, because the silencer fairing is made of aluminium on all models. Included in the delivery are the black aluminium rear silencer as well as a dB-Killer insert and a stainless steel retaining clip.
When it comes to tuning the performance, increases of about 8% can be expected. This also depends on the manifold used: With catalytic converter (51003KZ) or the racing manifold without (51003MI), but where the EG-BE expires.
