I'm using a 60 amp alternator and the "old-style" Lancair 3/4C exhaust system. The carb. heat and cabin heat outlets that come off the bottom of the heat muff collide with the bottom of the cowl. I spoke to Vern at the factory and he said the exhaust system was redesigned to accomodate the 60 amp alternator. I'm not sure which year this occured, but if you bought a kit and exhaust system back in 1989, like I did, your probably going to have problems. Even if you use a smaller alternator, your SCAT tube clearance coming off the bottom of the heat muff is minimal. I would rather not let the SCAT tubes lay on the cowl since the vibration will probably wear a hole in the duct but I doubt I'll be able to avoid this condition.
