great piece for my GSX-R 600. Was easy to install. I ordered the level 1 baffle with the snap ring. Sounds great and has a little more punch.

Austin Racing 2024-2025 DUCATI HYPERMOTARD 698 MONO TWIN EXIT SLIP-ON EXHAUST SYSTEM

Great product and excellent service

The product's quality is commendable, and the service provided exceeded expectations. Although the exhaust system was initially estimated to be delivered within 4-5 weeks due to a backorder, the item arrived within 1.5 weeks. Furthermore, communication was consistently effective, with regular email updates provided.

Yoshimura BLUE Japan Machine Bent R-11Sq R Titanium Cyclone Dual Bke cover Exhaust For Hayabusa 22-25 110-592-A16G0

Nice small footprint pipe

The pipe performs well with a lighter smaller footprint. They did fit the 2025 Tenere 700 US model but came with two O2 sensor bung holes even though the US 25 Tenere 700 only has the one up front. Their online picture of this pipe only had one. And there was only one plug provided. So if you wanted to remove the sensor entirely you'll need to buy another plug separately.
