manifold advice?

[Jakey]

There are reasons why FP products are generally higher priced that everyone else's. Buy the FP manifold and call it good, you won't be disappointed. You're only wasting time and money if you buy SBR shit or any of the GT manifolds. Go read some of the posts on Toonerz by Robert Young discussing his FP manifold, it's not all about quality of casting, it's also about fluid dynamics.
