that exhaust leak can really do some damage ( to your times). i was suprised at how slow i was running w/ the leak. now that its fixed i havnt been back out to the track to see how it runs. maybe i might go this friday but who knows.
the reason why no one can make a good uppipe isn't their fault. its b/c subaru put a crappy flange there. theres only 2 connecting points for one of the most crucial connections for your exhaust. very junky design. if u get, say, a maxim works headers, then the whole setup includes the uppipe part of the exhaust, but its all one piece of pipe comming from the exhaust manifold, so you don't hafta worry about connections - 1 piece design, very cool.
