Hello, im having no luck finding a exhaust for my r4360-20. it has the 4 bolt style on the port. not the spring later style. would be from a c-119 or a few other planes.ill take almost anything whole or parts or if you know of anything please contact me. its for a ground runner display engine. my short stacks are making a mess during runups and dont look nice. Thanks for looking Robert.
