BTM Exhaust Kit Old Version 2019-2025 The kit has a valve from Al-Hajri headers welded to it, and the valve gate has no leaks at all, double gates to withstand. The kit is fine, and there was a leak, so I installed flanges instead of the clamp system and welded a connector. And the last two connectors for the bumper outlets are clamps. And a note, the kit was very long and wouldn't fit, so I cut some off, and it doesn't harm it at all. But the kit is fine and has only been used for 8 months. Bumper outlets Purchase price of the kit was 4100. And the double valve was 650. The asking price is 2700.
