So, anyone have a dual exhaust setup on their Gen2? I know functionally it probably has little to no benefit, but aesthetically and the sound are the benefits for most people. I am considering fabricating a dual setup and was wondering if anyone else did theirs and if they are willing to take some photos. Since it has dual converters, one could run a separate pipe from each. Or do like old school mustangs and make an H-Pipe. Or could go on the simpler cheaper route and just put a Dynomax single inlet, dual outlet, muffler on and split the tail pipes out. Really limitless options with the right imagination.

You'll find that your exhaust flow will be more efficient if you use a single larger pipe. It has to do with the friction that the inner walls cause. Increasing the pipe size by just a small amount adds only a little extra wall on the circumference, but having twin pipes with the same amount of total cross-section has a lot more wall, and more drag.

Take the single and upsize it to the muffler, then pop some dual tips out of the muffler. Better flow, less cost, way better looking. :)
