help!! i have a viojett fan with a bvm .91 and puffer pipe needing it to be installed in a yellow f-4 requiring the pipe to be angled down 12 deg and to the left 8 deg thus flowing out of the left exhaust. as you many know, this system is designed with the pipe running straight back from the rear exhaust. the engine has no ability to bolt on an adapter as the os engine allows and the pipe's length would extend about an inch pass the exhaust rim.

i would greatly appreciate being given the e-mail or web site to someone that could help me with this problem. it would seem that this particular scenario should have been solved and may need an answer for many of us using the bvm engine in such an application that does no allow for the pipe to run straight back. yellow sells a short twin pipe for this f-4 but the exhaust ports are of different diameters unless changed in the last few years to match the bvm.
maybe someone can help me not have to purchase another engine and keep using the bvm which has done well.. many thanks..........
