Title: 8v gasser manifold-which one?
Post by: Wayland on November 20, 2009, 11:51:02 am

I have an 84 gas Jetta with a twin tube downpipe, but it has a toilet bowl type manifold. Is this a worthwhile upgrade for 1.6na, or should I look for a bolt on type twin tube downpipe?

I've always been told the toilet bowl style is the worst for flow/performance.  Look for an early dual outlet, dual d/p set up.
