Default Problem with Saito 82 installation

I am in the process of building a scratch Boeing P-26 Peashooter. When I did my engine install today I found that the exhaust mainfold is about 3/4" too short to provide clearance on the fuselage.

I am not really up for spending $45 for a flex pipe. Anyone know the thread size x diameter of the exhaust manifold ? If I have that I may be able to find a union and bolt 2 standard manifolds together.

Any other suggestions ?

Thanks.

Are you trying to mount the muffler outside the cowl? Have you considered mounting the muffler inside the cowl entirely and just porting the exhaust out?

The 82 is 12mm but watch the thread pitch

Try this straight pipe?.... http://www.horizonhobby.com/Shop/ByC...ID=SAI182TD74A

enjoy,

Jim

Camp:

The FA-82 has 12 x 1.0 mm thread in the exhaust port.

Some other popular four strokes have a 12mm exhaust but the thread pitch is different.

Enjoy,

OK, I am going to start checking the pipe and possibly other brands exhaust manifolds.
