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.

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.
