I use to different size pipes on my stacks. Although a stepped header generates more low-pressure waves than a non-stepped design, its waves are weaker. Exhaust volume increases with engine rpm and fuel delivery. Measure at the end of the pipe. Exhaust Pipe Size Estimate: A good section of straight pipe will flow about 115 CFM per square inch of area. " Following Pythagoras' theorem, the first number, or true offset, is calculated by taking the offset squared and adding the rise squared to obtain the true offset squared. 17" on the factory system. This can only be prevented if the pressure at the exhaust port is greater than that in the cylinder. First you’ll want to take the exhaust clamps from your factory pipes and slide them over your new exhaust. 250") and subtract from the OD. It need not be a car exhaust pipe; it can be other metal pipes, and I'm even sure it will do well on PVC large diameter tubing. A common belief is that by reducing back pressure in the exhaust system you will automatically gain horsepower. This will convert your weak single exhaust to a powerful dual exhaust system with a Performance muffler that will fit 1994 through 2010 Dodge Ram trucks. I got a catback exhaust system, that SR*S one and i have an all stock exhaust system right now. Running a single pipe from the engine to the muffler, then splitting the pipe behind the rear bumper doesn't accomplish a dang thing. Pipe Size = √[A x (1/0. If you want to keep birds and other critters out of a PVC vent pipe, you could have your dog guard the pipe, but there's a better way. to 2-5/16 in. To find the inside diameter (ID), double the wall thickness (ie. 5" will maintain better low/midrange velocity than a single 3" (especially with an X-pipe) - remember, each cylinder bank is mainly seeing the pipe diameter, and exhaust pulses only come one at a time regardless of how many pipes you've got.
