Scale Detail Accessories / Glass Pack Mufflers With Tips - 4 PC. This item is for use on 1/24th 1/25th scale models. These Glass Packs are different than any others out on the market. They are 24 inches long and are DRILLED ALL THE WAY THROUGH to fit over 3/32" aluminum tubing. This allows the builder to slide them on the tubing before making any bends. Once the exhaust system is installed, simply take the edge of your hobby knife and line them up perfectly. No more cutting your tubing three times and still having it too short on one side. The tips are also drilled clear through for added realism and are designed after the 12 inch "BIG WAZOO" tips. Please submit payment through PayPal.
