True Duals
I don't think this setup is considered true duals but I wanted to double check. Runing two pipes from each header into a flowmaster 40 that has two inputs and two outputs. Is this considered true duals since you have two pipes going into and out of the muffler, or since they are both going to the same muffler regardless. Also, is this efficient?

RE: True Duals
yea its true dual but what engine do you have? if its a v8 with one muffler you might be getting a lot more back pressure using only one muffler..i know dodges tend to thrive on some back pressure to keep low end torque but that might be a lot of exhaust flow for just one muffler

RE: True Duals
i've never heard that called true duals. true duals uses two mufflers and two cats with each pipe running seperate from one another. people add an x pipe or an h pipe to equal out the pressure and make it more efficient. two in and out one muffler isn't any different then having a y pipe at the headers and a y pipe after the muffler. that one muffler is gonna have about the same restriction.
i could be wrong in your guys idea of true dual exaust.
