Which exhaust should I choose for my R33 GTSt?

Sorry for biting your head off there.

no probs, I didn't get upset

I just did it to be different. To attract less attention (it may or may not succeed in doing that) and because I like the appearance of two largish stainless tips.

true, I prefer the sleeper look, coz mainly I dont want to attract attention from others (not cops, but just general public). I hate the way my Super Dragger tip looks (5" is ric0ckulous IMHO), but i got it b/c it was a great bargain.

Overall flow is probably down on the average 3, 4 or 5 inch tip but im sure there are other factors in the exhaist that are more restrictive like my cat-convertor which make the overall difference trivial.

true again, but i guess it only makes a difference at WOT, and very high rpm where you may get more back preassure b/c of that muffler. And I dun know about you, but WOT + (6000+) rpm is maybe a once or twice a week thing for me these days..... just cant get to those rpm's in traffic!
