After headers and test pipes being installed....
there's a problem been a bug to me, after installed the parts, i think in the mid section of my exhaust system, could be the section between test pipe and below, there's noise like air leaking out with fast ticking sound, but my rpm doesn't seem to act weird...could it be because the stock muffler or exhaust system isn't good enough any more for the hp that im boosting out?
i can hear the sound very clear as im reving over 3000.
please help me out. thanks

hmmm... sounds strange, when I purchased my cheapo ebay testpipes they leaked, and they made a sound like someone with a lisp trying to whistle. the ticking sound could be the debris that is built up from the packaging that is burning up. as far as the exhaust, there's plenty of folks on here with that setup and no problems. you should check all your gaskets and bolts to see if everything is tightend properly.

I don't think you have a leak. I've had that sound for a while now, and I've been through 8 exhaust setups. 7 of those setups have had this sound.
I'm pretty sure it's because the tubing isn't lined up just right. The inner diameter of the various pipes might be the correct measurements, but if they alignment of the pipes is off by even a millimeter, the exhaust gases can make a hissing sound as they flow over the misaligned pipe edges.

If you think you have a leak, try this. Let the car and exhaust piping cool completely. Then start the car and place your hand in close proximity of all the catback exhaust joints. If you feel pulsating air at the joint, you have a leak. You should be able to lie on your back from the side of the car and access all the joints. There's no easy way to tell with headers and header to test pipe connection though because of the limited access unless you jack up and support the car.
FYI, just because the gaskets are new, doesn't mean they can't leak. A lot, and I mean a lot, of aftermarket exhausts have issues with the exhaust flanges sealing. The problem is because the flange is too thin and when the flange gets welded, the heat distorts the flange and the gasket can never adequately seal.
