We bought a '68 Nova to race and I am putting in a 510 BBC that is supposed to make 720hp.
I want to build an exhaust system so I can run in the street legal class. The car has a set of 2-1/8" headers with 4" collectors. I would like to "over build" it a little bit, for when we step in power to about 850hp. What mufflers provide the least amount of hp loss? What size pipes? Should I use a x-pipe if I can even get it under the car?
