This is a Omega Intruments digital exhaust temperature gauge with clamp on probe. This installs in the header to read and analyze exhaust temperatures. It includes the probe and is capable of reading two probes if you were to buy another. The probe alone is around $100 from Summit or Jeg's (or anywhere else for that matter). I'll take $135 shipped. It works PERFECT....guaranteed!

 

TTT. This is over half off.
