How to Achieve More Flatplane-like Exhaust Note? Has anyone successfully incorporated an exhaust system that turned their LS into a more flatplane sounding engine?
I know a 8-to-1 merge collector will do the trick, but obviously packaging such a collector is not feasible in conventional cars.
Anything else?

Yes, 180* headers do achieve that sound although 8-1 merges are a bit more buzzy. However, packaging 180* headers into a FR car or anything that's not mid engine, really, is as difficult as cramming a giant 8-1 collector in somewhere. If someone has done it, I would love to see that exhaust.
Here's a shot of a 2nd gen camaro, built by RoadsterShop. 180 degree headers are possible...

I haven't heard the car run personally, but was told it sounds very good. I'm not sure it's possible to achieve the flat crank sound your talking about, without actually redesigning the engine to a flat crank assembly.
I ran 180 degree headers on a late model asphalt car from time to time, and although the sound was different than my standard cross-over headers, it sounded nothing like a true flat crank engine.

Exhaust Tuning The above reports are known to be correct.
I would like to add "primary" length.
Measure the Primary Tube, the best sound will occur when "equal" in length, a
length within 1/4" on each pipe.
The exhaust outlets, after the collector, two, three, four, six are possible as would eight or more will cause an effect of which all are different.
The number of "outlets" has great effect on Song.

I'm wondering if a Flat 8-1 collector can achieve the same note. Obviously packaging a giant cylindrical 8-1 is not possible, but I think the circular puts the exhaust gases in a certain firing order that a flat 8-1 might not do?
Lola-332 F-5000 Exhaust My Lola, a T-332, had an exhaust built to fit by S/S Headers in Anaheim.
The exhaust was over the DG-300 yet under the rear wing.
This WAS a two collector INTO a "single" 4" bore muffler.
The muffler center was made of "fiber metal" a left over, damaged, piece I was given due to my design of the muffler for the B-2 Bomber.
That "damage" was end damage only, when cut to my one 1" less length requirement, it was a perfect fit.
The sound of my car was that of a F-1 or Indy Turbo.
One race I won, of many, was the Palm Springs Gran Prix.
The song of my Lola @ 200 MPH (300KPH) as it "echoed" the streets of PS, was known by ALL.
Lance, BTW you may have seen/heard this sound on TV.
