"good sound" is not definable. i'm sure there are people out there that think civics with a fart can sound great.
take that sticky with a grain of salt. 9 out of 10 people on this site with true duals have an X-pipe. what do you think is going to get recommended more and praised more? "the best exhaust is the one you have," remember that. very few are honest and actually research this stuff. most just jump on the bandwagon and get whatever everyone else has. look at the new flowmaster single chamber fad. a few months ago, a handful of people on this site had them and most people didn't even know what they were. now everyone wants single chambers. take it all with a grain of salt.

I'm sorry my friend, but like other experienced posters have stated, this is absolutely WRONG.
What might help you (and others who might be confused about why there can only be one right answer) is to get behind the physics of what is going on, to better explain the results.
You see, and well-built X-pipe scavenges exhaust gases, much like long tube headers. Alternate to popular belief, long tubes shine in the midrange, where the scavenging effect most takes place.
By definition, scavenging actually increases the airspeed of the exhaust gases to a point greater than they could support by themselves. In other words, the 2.5" bassani X on my previous car flows better than 2.5" individual pipes.
Now, an H - pipe DOESN'T SCAVANGE. That is fact. Nor is it designed to do so. An H-pipe is designed to even the pressure from both banks of exhaust, so the pulses are equalized, for SOUND PURPOSES only. This is well known hot rodding theory, from many, many years ago. It is undisputed.
So, that is why an x-pipe is a better design than an H-pipe, especially for midrange tq. I hope this helps explain what is really going on here. If there are any questions or concerns with what I wrote, don't hesitate to respond, right or wrong: I emplore people to respond so we can successfully put this issue aside.

I agree with the rest of you vehement rant though

Nope, they are well on their way, just wrapping everything up We pushed their release date back a bit due to other things that had to get finished first.

Most likely it would have to be 2.5 to go over the axle.

that's what i would go with. i'd probably go with an h-pipe though.
on a side note, where would the bullets or mufflers be placed? i want to be able to keep my cme set up.
I'd buy one if it was available..would prefer a 3 inch into a 2.5 inch over the axle and out the back setup .. don't need stainless either..
