Exhaust section # 3, stainless, Vedeneyev M14-P, PR, M9R
Vedeneyev cylinder numbers are designated by standing at the front of your aircraft looking backward to the tail. The top cylinder is number one, and the other 8 count clockwise.
If you are trying to identify a particular exhaust section, consider the curvature of the exhaust flow and you'll notice that exhaust sections for jugs 2 through 5 ( seen on the Left side of the engine compartment), when held with the Exhaust nut forward and viewed from the outside, or convex side of the exhaust ring, will show sidearm curvature in a clockwise curve.
Exhaust sections 1 and 9 through 6 on the right side of the motor, when held with the Exhaust nut to your right and when viewing the outside curvature of the exhaust ring, will show sidearm curvatures that are anticlockwise.
The product page for each Exhaust section in the store has additional pictures to assist you. Please call us at 619 933-2571 with questions
