Many members who run test pipes have hissing sound. Hiss is normal. It is not a leak. Some say it comes from the y-pipe flex sections..

Test pipes make all sorts of strange noises.

test pipes definitely do sound different on every car,even if its the same exact setup.

But if everything is tight like you said, then i wouldnt worry about it being leak.
