fuel pressure setting and exhaust
 

I have a 13 B semi PP with weber 51 carb. (newly to me e-prod car) Where should I be setting fuel pressure as a starting point.

I will be required to quiet this down to 94 dba . Looking for exhaust setup ideas.

also interested in getting in touch with others running a similar setup.

I've always run ~4 psi with webers.

3.5 psi . Running a single 3" into a Magnaflow filled with lava rock. Racing Beat header.

the competition book says 4.3psi, so something like that should be about right.
