No, the Invidia system is not angled, it just comes straight out. I have it on my 98 EX and I love it.

I am probably just going to get the 5zigen axle-back.

I was afraid it was going to sound high pitched and ricey, but the only time it really gets loud is 5000+ RPM and I only hit that on the highway. As for performance, as long as you have a perforated core type muffler (meaning, without the baffles) you're going to get about the same improvements in exhaust flow on any given brand of exhaust (assuming they are all the same diameter). Basically all you're doing is reducing the psi in backpressure. Stock pipes usually generate about 12-15 psi whereas an aftermarket system can reduce it to about 6-8 psi. Just to give you a better idea, rally cars using test pipes (straight back, no cat or muffler) generate about 1 psi.
Do you have any pics? Where did you get it? Is it this one: http://www.robearracing.com/pd_invidia.cfm

Does the angle of the muffler/exhaust give any difference in performance, or is it only for looks?

Yeah that's the one. I got it through a local company called "Street Dreams". I originally wanted a greddy sp-2 but the guy at the store suggested the Invidia and cut me a good deal.

No and yes. The angle of the pipe has nothing to do with performance. However, the bends in the pipe may effect performance if they are not mandrel bends. A mandrel bend means basically that the bent metal has been smoothed out on the inside, bent by a machine, to allow the exhaust to be more free flowing. Non-mandrel bends will effect performance very little if any. The Invidia exhaust has mandrel bends.

Uh, where did you find this info?
