A new person to muscle cars basic exhaust question

[Quiicksilver]

hello all

first post

I am a long time BMW E36 BMW enthusiast who has tuned 3 differant bmws, i currently own an e36 M3 and have grown up in a family who collects muscle cars, so i bit the bullet and picked up a 1970 Chevy Nova with a 350 .030 over





My question to you is the car is running hedman headers to a 2 INCH exhaust, now my guess is that a 2 inch exhaust with some off name mufflers is a very restrictive exhaust, the motor has a eldbrk. 600 CFM carb and intake manifold. So i guess there is lots of air coming in, but going out is another story? what would be prime to upgrade to? a 3 inch or 2.5 inch, IS THERE ANY KITS MADE FOR SIDE EXIT EXHAUST?


thanks for your time and looking forward to replys.
