Swapped out my Ark Grip for the Fast Intentions Carbon Fiber Non-Resonated CBE. Even with Test Pipes, the Ark was way too quiet for me. The Fast Intentions is noticeably louder, but it still doesn't scratch that itch. I've seen many comments saying how the Non-Res FI CBE + Test Pipes is an insane combination, which is certainly an overstatement. Don't think I'll be content until I go Tomei or GT Haus in the future.
The Ark is for sale if anyone in the Tri-state Area is interested.
