Now more Horsepower and unbelievable Prop Twisting Torque is possible simply by installing LEES’ new “Cross-Flow™ dual exhaust system. LEES has just completed the final test fit on a Cessna 185 model aircraft. The aircraft information listed below is for the airplane used for test fit. Dual 2-1/2” tailpipes exit the lower cowling. Two tailpipe exit holes will be required in the L/H and R/H side of lower cowling. Exhaust pipes in the photographs were tacked for final fit up. The exhaust is presently being fully TIG welded before being sent out for CMM.

This exciting new “Bad Boy” dual exhaust fits the later model Cessna 180 models that have a tighter fitting lower cowling than the Cessna 185 models. The only difference is in the tailpipe layout. We are going to have both Cessna 185 and post 55 Cessna 180 tailpipes installed for dyno tests. click here to view photos
