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.
