Corrugated Blue Very Hi Temperature Silicone Rubber Wet Exhaust Hose, 1.00 Inch ID, Up To PSI

For most wet exhaust applications, 350 degrees F continuous is solid coverage. That said, the closer you are to the point of water injection, the hotter things run, so placement matters. The installation guidance for this hose specifically says to mount it far enough downstream from the water injection point so the temperature at its location stays within that 350 degree rating. If your routing puts it in a spot where heat stays consistently above that threshold, Trident does make a red XHT version rated for 500 degrees continuous. But for standard wet exhaust placement downstream of injection, the blue VHT handles it well.

The hose is 1.00 inch ID and 1.50 inch OD.
