Pre 55 Cessna 180 Dual Exhaust System is Approved!!

The STC was issued on September 12, 2011. The model aircraft it was approved for have serial numbers 604, 615 and 30000 through 32661 that are equipped with FAA approved installation instructions of Continental O-470 K, L, R or S model engines.

The price is $4995.00 and is complete with: 321 SS R/H and L/H 3-1 US Patented Collectors, two new mufflers, new muffler shrouds, tailpipes with new exhaust flange gaskets and tail pipe clamps.

The back pressure has been greatly reduced with the 1-3/4” primary tubes being large enough to handle a 550 engine. The primary tubes also incorporate a slip joint to accommodate expansion and contraction and do away with the original 2 part 1-1/2” beaded end risers that were inherent to leakage and very difficult to remove.
