Has anybody had the chance to see if there is any significant difference in spool time between these two manifolds? I want to get rid of this SSautocrap BEFORE it cracks...but I don't to sacrifice any spool time.

 

you might see at most a 500rpm difference, not much too worry about to have a manifold that won't fall apart

 

an ssautochrome mani flows like absolute ----, the runners are undersized and its not a real collecotr. lsd offers solid manis, and a properly built short tubular, will run circles around that dumb paper weight your running. shorter runnered manis generally spool faster anyhow due to less los of thermal efficiency of the exhaust gas through the surface area of the runner,

 

Sounds like I know what I'm goiong to do...Thnx..
