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.

Since this is in the 'how to' area and we're all friend with the same goals I thought this would be additional/helpful information. Good education/additional information on exhaust engineering.

Here's a clip that explains how Flowmaster's chambered muffler technology works.

Ben,

There definitely is truth in that you want to reach and maintain the optimum exhaust velocity for maximum horsepower, be it through a single or dual exhaust system. Give our guy Steve a call here at 707-544-4761 x452. Steve will be more than happy to discuss what you’re trying to do with your car in detail (current mods, planned mods, etc.) and get you the scoop on how to make sure that your exhaust system is setup properly.

Thanks Ron. I'll give Steve a call.

I tried to watch that video you posted above but the link didn't work. I bought a set of 40 series for my Nova way back in the early 90s, but not sure I ever learned how the do what they do. I'd be interested in watching if you get that link fixed up.

Here's a link to our Chambered Technology 101 video on the Flowmaster YouTube channel. Hope that this one works for you.
