LT headers worth it on 2001+ C5's
Just discovered that the exhaust manifolds on 2001 and up C5's were revised from the earlier design and are more efficient. This being the case, how much can one expect to gain from Kooks/Dynamaxx LT's? Do the stock manifolds flow well enough to support a head/cam upgrade?
Also, what's all this I've been reading about LT headers sounding raspy/tinny? Sound-wise, I much prefer that mellow woofly-warble idle and over-run sound, with a nice deep growl at WOT. Personally, I really don't care for the harsh metallic-sounding over-run sound I've heard on a lot of video clips of modded C5's when the driver lifts-off. What causes this? Stainless steel headers/cat-backs? I wouldn't want my car to sound like a NASCAR oval racer... I don't think it suits the C5's image. I prefer a more exotic, subdued engine/exhaust note... ever hear an Aston Martin V8 from a Vanquish, for example? TVR V8's sound great, too... that's the type of sound I'm looking for.
Cheers,
Ian.

Some of your questions are answered here.

For the rest :
1> All long tube headers will be SIGNIFICANTLY louder than stock. The tube walls are thinner and you will hear the engine more.
2> Choice of cat-back is what determines the "tinny" sound. I have Borla Stingers 2 tip and they are both VERY deep and VERY loud. I love it
3>Head/cam needs real long tubes. Installing anything else is a waste of time and money. Engine has to breathe. End of story.
4> Hear headers & cat backs in person before making a judgement. All videos do NOT produce significant bass - you are missing 90% of the wonders of longtubes by listening to videos, trust me.
5> I have Dynatech Supermaxx headers, high flow cats, x-pipe and Borla Stingers 2 tip cats. If you hang out in the Northeast section, you can probably hear my car in person - I've started hanging out with the NY/NJ gang.

Headers Flyby - very loud
