Exhaust Questions

[akram]

Going up in size of the exhaust pipe on a single exhasut you are increasing how fast, and how much at one time, of gas the vehicle will expell. Now with duals you are doing the same thing but usually with two smaller exhasut pipes. It is also usally cheaper to do just a single. The bends and such play a big role in it also. There is a limit on the size. Once you hit a certain size tubing it's pointless to go bigger and then there is the debate of back pressure.
