I’ve been investigating what kind of exhaust system to install with the rebuilt B20 and would like some opinions. Although there has been some other postings about the subject it seems that it’s an individual preference kind of thing and divided along things like type of rebuild, flow, fit and guietness. I’m tempted to get the 2” sport exhaust sold by Skandix. I wonder if the 140 sport exhaust would fit onto my 122? It looks like it straighter.
FYI my B20 has:
An Isky Street Performance Cam with new lifters
New rings and is bored out at 030 over
A fuel injection head that has been rebuilt and will have an SU set up on it.
A Cranes electronic ignition

I wouldn’t mind if the exhaust rumbles, but I don’t want it LOUD.

My questions for BBorders are:
Would I get enough flow from 2” system to “maximize” the power available?
Can I go over the axle (my preference) and still get good flow?
Should I use a combination intake/exhaust manifold, or use a two piece set up?

Many Thanks.
