Quality and Sound

The shipping was fast and smooth. The installation was really easy the only thing you will need is a “servo buddy “so the check engine light wont come on. Other than that, it looks and sounds amazing. Very Satisfied with the purchase.

High End Exhaust

I purchased the Graves Titanium slip on for my 2024 KTM 500 EXCF. The quality of this muffler is second to none! It's super light weight. Installation is easy. Graves has done it again! Buy one. You can't go wrong.
