True Dual Exhaust help
Hey guys I went to my local exhaust shop last week and ordered everything for my custom exhaust. I just have a few questions. FYI it's a 2007 Hemi 5.7
1. I was orginally planning on using and X-Pipe for the True Duals but the exhaust guy told me it the sound I told him I was looking for which was Deep and loud he said running true duals with generic chambered mufflers without a crossover was what I'm looking for. Do you agree? Or should you always have a crossover? I'm running 2.5 pipes of each cat.
2. Also is there any disadvantages of running both the pipes down a single side since the left bank has a longer pipe to go out?

The way I was taught, and I'm not saying this is the "only" way or even the "correct" way, but I was taught in the '80s by a friend who owned a local exhaust shop in upstate NY who was very highly regarded.
He told me to ALWAYS use an "H" or "Y" or "X" pipe, something somewhere along the exhaust to equalize backpressure.
So, I personally, have always used some sort of pipe connecting the two sides at some point. Right now, I have a short, but fat, "Y" just before my SI/DO muffler, but I've used an "H" before the dual mufflers and even simply used a DI/DO muffler whereas the system would otherwise be true dual.
Now I know many guys run a "true" dual exhaust all the way with no issues at all, so take it for what you will...

The H will have a deeper sound than the X. The X will sound a little ricer like a Corvette.
A Chambered (aka Flowmaster) muffler will not sound deep. They are usually hollow sounding. Something like a Magnaflow, Borla or a good turbo muffler will be deeper in tone.
