These may be stupid questions, but what the hey? Also, no disrespect to any of your exhaust systems. I myself am still running the tubes that came on my factory SS. So, here it goes:
Has any 4th Gen F-body owner looked into, purchased, fabricated, or had any experience with using an X-pipe system instead of a Y-pipe? While on the subject, has anybody switched to true dual exhaust, wherein the left pipe stays to the left, and right stays right, and never the twain shall meet? Is an X-pipe actually a true dual, or does the X-portion allow gases from the left and the right to mingle?
Is the fact that there are two pipes sticking out of the last few feet of plumbing (i.e., from muffler to tips), the only claim to SLP's "dual-dual" nomenclature? In other words, is "dual-dual" merely a cosmetic thing? This system still uses a Y-pipe to merge the left and right banks into one, before this one pipe gets split into two tips after the vacuum cleaner-shaped muffler, right?
I remember looking up the skirt of a Mustang GT one day when I had my SFC's welded on. The owner had a pair of Flowmasters installed. I don't recall seeing any Y-pipes underneath his ride. Do the current Mustangs (4.6L, not Fox body 5.0L) come stock with X-pipe or true dual exhaust systems? Is it their non-Y-pipe setup that makes stock Mustangs sound so much more guttural than stock F-bods?
Thanks in advance.

"has anybody switched to true dual exhaust" Has been done, Most run the two pipes down the same run as the original single pipe.
"wherein the left pipe stays to the left, and right stays right" Can be done, but loose lots of ground clearence.
"Is an X-pipe actually a true dual" I would say no. But I think you'll get differing opions on this.
"is "dual-dual" merely a cosmetic thing" Yes and yes to the next question also.
"Is it their non-Y-pipe setup that makes stock Mustangs sound so much more guttural than stock F-bods" There are just to many variables to make this kind of blanket statement. Almost every engine variable will effect the exhaust sound. Number of cyclinders, size of the engine, compression ratio, engine timing, firing order, header type, header design, header primary and secondary tube length and diameter, collector length, tube wall thickness, type of CAT, total length of exhaust, single or dual pipe, and muffler type, etc., etc. Generally, and this is very general, the lower the compression ratio the lower the exhaust tone.

True duals with x pipes have been done, the problem comes with the rear axle and panhard bar assembly. Most choose to cross back over, go over the axle on the right and then back to a split at the rear.
The "Dual dual" simply means dual rear exits with dual tips.
The difference in sound is primarily due to firing order - not the y pipe.
Hope this helps.

W W, it looks like a plumber's nightmare with all those bends and welds.
PS: Thanks for the pics. That's the first time I've seen pic's of a dual exhaust on an F-body.
