FAQ
Why titanium over copper? Copper is fine but Titanium is much stronger, more resistant to corrosion, lighter, less toxic, and less conductive of static electricity and heat transfer vs copper.

Why is it also expensive? The Big Tube is not 3/4 or any metric size, Buckshot Racing has the Super Tube custom-made to match the Mercury OD / ID exactly to ensure fit and proper cooling.
