Our silicone hose is the best hose for short connections.  It helps isolate exhaust systems from engine vibration and movement. Helps solve slight misalignment problems.  Easier to install and seals better than black rubber and some other brands of silicone hose.  It will not become brittle, hard or rigid... remains flexible. Resistant to heat, aging, exhaust gases and the ozone.  The smooth, shiny finish enhances your engine room appearance and is easy to clean.  SAE J2006 standard compliance and labeling, including compliance with NMMA and ABYC exhaust hose standards.
