Superior Manufacturing Quality

• The products were made by “Lost Wax” production method with SUS304 alloy.
• For overall high performance we have designed the pipe diameter to be 41.5mm in diameter & 2.5mm in thickness which brings out the high quality sound.
• Highly accurate TIG welding.
• Smooth bends to decreases exhaust flow interference.
• The pipe angles were designed to increase exhaust flow efficiency.
• Attention to details with the smoothness of the internals of the product.
