BTM Exhaust System, Old Version 2019-2025 The exhaust is welded with a stopper from Al-Hajri headers, and the stopper gate has no leakage at all. Double gates were installed to withstand it. The exhaust is in good condition. It had a leak, so I installed flanges instead of the clamp system and welded a connector. Note: The exhaust was very long and wouldn't fit, so I cut some off, which doesn't harm it at all. The exhaust is in good condition and was used for only 6 months. Bumper outlets. The purchase price of the exhaust was 4100. And the double-gate stopper was 650. Best offer. The highest offer so far is 2500.
