Modified Log manifolds have a 2 1/8″ outlet versus the 2” outlet on stock manifolds. Manifold has 2 3/4″ flange bolt pattern.
NOTE: Due to “under the plug” design, stock type motor mounts must be used. Also, some type of spark plug shields are a must when running angle plug heads.
The “under the plug” design Log manifolds are available stock or modified. If your chassis or rules don’t allow the use of “Center-Dump” manifolds, Log manifolds are the way to go!
