Many motorcyclists agree that Yamaha’s CP4 engine – whether in the YZF-R1 or the MT-10 – is one of the best-sounding motorcycle engines ever. Coming out of the factory, the strong sound of the exhaust is already menacing, but it becomes even more exciting with the addition of a quality aftermarket exhaust system.
Now, depending on where you drive, you’ll either want a racing exhaust or a road-use setup. Fortunately, Yoshimura offers both for the 2023 Yamaha MT-10. Both configurations use Yoshimura’s AT2 silencer, complete with a carbon shield that adds a sporty touch to the already sporty hyper-naked machine. Yoshimura’s AT2 Race Series is a ¾ exhaust system that eliminates the catalytic converter from the bike. Naturally, this means that this exhaust system is not legal for use on public roads, as it no longer complies with emissions and noise regulations, so it should remain on circuits only.
For riders who want to keep their bike legal for public roads, Yoshimura offers the Street Series, which consists of the AT2 silencer and a connecting pipe that is mounted on the bike’s original catalytic converter. This configuration is not only quieter than the Race Series, but also maintains the bike’s emissions compliance and is therefore legal for use on public roads.
Of course, users looking to extract maximum power from an aftermarket exhaust will want to opt for the ¾ race system. Yoshimura claims that the AT2 system increases power by two percent over the original system, while torque increases by 1.7 percent. For a bike that puts out over 150 hp, this is certainly impressive. What’s more, the AT2 Race Series weighs half as much as the original system (4 kg against 8 kg).
