Exhaust manifold design

[darrenjlobb]

A log manifold will more more than surfice for just about any application on cars like these.

However you cant beat the noise a properly designed stinless tube equal length manifold produces..makes the engine sound much more in tune when its on song, its something you cant do without once you have had imo.

As for cracking...the only time ive ever had issues is when things arnt supported correctly / welded to close and heat has no where to go expantion wise.

My manifold i have now has caused no issues at all.

But a simple log manifold up the side of the block will quite happily flow all you need for mega hp all day long, the head will become a restriction along time before the manifold!
