I love the Titanium Exhaust Manifold on my 2024 Rocket 3 GT

I love the Titanium Exhaust Manifold on my 2024 Rocket 3 GT, The fit was perfect and look was just as good. The true beauty is how it blued & red coloration after the first few heat cycles. The carbon fiber shields are a great touch but the fit and finish are fantastic. The bike looks great and performance is even better.

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.
