Im not sure if this section is the bes one or engines. ANyway - I received my 4-pipe Vetterman exhaust via Van's. I am fitting the pipes to a Lycoming IO-320 that has a Superior cold air sump and induction pipes.
The exhaust pipes for cylinders 4.2 and 3 (that being the ordered I fitted them in) are all fine. In particular cylinders 4 and 2 sit together very nicely.
THe problem is with cylinder 1. It is far too close to the induction pipe and the only way I can get it to fit at all is with the section after teh ball joint at a very strange angle.
I hope the photos are clear enough to show the problem. Can anyone identify where I've gone wrong?
Here you can see the pipes from cylinders 2 and 4 nicely aligned:
Here the pipe from cylinder 1 is going off at a funny angle:
And here you can see how close the exhaust is to the induction pipe
Viewed from the front it looks like the top section should be longer and straighter to get the pipe below the induction pipe and outside the pipe from cylinder 3.
Many thanks for help.
