Dual Exhaust Questions... Options

[tonytutino]

i was thinking about getting dual exhaust pipes coming out cause i thought that would look pretty sick, but does anyone know about how much it'd cost to get another semi-circle cut out in my back bumper for the muffler to come out under? cause i can get the piping done for real cheap but i dont know how much the actual body work may cost, it seems like it'd be alot PLUS i'd have to repaint it... blah.

Engines breathe, engines breath better with less resistance, less resistance comes from straighter and bigger(to a point)pipes, on V6 engines or other multiple exaust manifold engines having straighter pipes means having multiple pipes(2) thus two mufflers, on 4 bangers the second pipe makes more resistance b/c it causes turbulance at its inlet and reduces efficiency.

On a side note, our exhaust manifold faces forward with 2 pipes on the left annd 2 on the right. What if we took a 4-2-1 style header and cut them off at the first intersection of 2 pipes. Making one piece that acts like 2 headers that are 2-1 style headers and then hook up custom exhaust systems and mufflers that are enev straighter and shorter(but they'd have to be a slightly smaller diameter, we could create the first functional Dual Exhaust for 4-cyl. Engines!!!
