How to Design a Custom Exhaust System

[Ben@SpeedTech]

Ron- I might also mention that the motor mentioned above that I've now installed in my wagon was in my 3100 lb w/me street/strip Nova, and ran 11.70s @110 through a 3" dual (no crossover) system with 40 series Flowmasters and 2.5" tailpipes exiting behind the back tires. That car had 4.56 gears and a 4500 stall, I shifted at 6500 and went through the lights at 6200.
