SUS304 stainless steel is used throughout. It's mandrel bent using the fewest bends possible for maximum flow and efficiency.
Significant steps have also been taken to reduce the weight of this system. Piping wall thickness is only 1.2mm. Exhaust hangers are of a hollow design, further reducing weight. To top it off, the mounting flanges are a reduced thickness SUS304 pressed steel type (as opposed to industry standard 1/4" to 1/2" solid steel flanges).
Amazingly, it's able to achieve all this while still coming in at under 93db!
PIPING: Single 70mm into Dual 60mm
TIPS: Dual 100mm
