View Full Version : restrictions in exhaust manifolds...

today i had a chance to take a look at a few log style manifolds....2 SSauto top-mount manifolds and a full race manifold. all i can say is that the full race, is perfect when it comes to any type of obstructions or restrictions in the runners, welding or flanges. as for the other two manifolds, i cant say that. which brings me to my point.

which would have more of an impact on HP?? log style or poor fabrication of a manifold?? (runners are off-ligned with flanges, and turbo flange has very choppy welding and choppy flow path)

Search for a thread enthalpy did about the power gains of the fullrace over the log manny.
