"Why Inconel?"

Unlike Titanium it will not burn through, it can be as thin as 0.37mm wall due to it's unrivaled strength.

By holding high temperatures this keeps the ambient temperature low, it also cools down very quickly.

Take a look :)

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.
