i just started to hear it i have an exhaust leak...i have a greedy header and test pipe...where normally would i expect to have the leak? i hear it coming from in front of me so its not from my catback...any ideas?

I think I might have the same problem. Whenever I accelerate, or push the gas when I'm in neutral, I hear a "whooshing" sound, kinda like I have turbo. I took it to two different places, and neither of them could find it. The last place told me that it could be the "two plies of the final portion of the header have separated, creating a gap of sorts." I have a DC ceramic header, and I don't know if it is two ply near the final portion of the header. If so, and Greddy's are two ply at/near the collector, this may be your problem.

Did you replace the gasket?

No, but the exhaust tech, who really seemed to know his sh!t, checked all the joints for leaks, and checked for holes in the piping, but found no source for the leak. So I'm guessing that it really could be a separation of plies in the header collector area. Now that I ain't goin' turbo, and might be getting some nice headwork done after I pay my bills, I might have to invest in a very nice header, or buy the JDM H22.

i was think/hoping that it is a leak on one of the flanges...and to fix it all i have to do it tighten one of the bolts or 2...wishful thinking i guess

... yet another quirk w/ Honda tuning. W/ enough determination, though, ALMOST any Honda quirk can be solved (w/ enough money, too, hehe).
