How can i explain it, mmm, let's just say that the car feels like an angry bulldog, the torque seems better at all RPMs and it pulls like crazy, no more slouching like it's the summer blues.

As for the sound, i have posted a clip on youtube:

Please hear the sounds and lemme know what do you think.
It sounds like something is wrong with the headers, a leak or a rub or something. That "blub blub blub" sound is odd, i would assume headers. Take of the little heat shield and re-tighten all of the header nuts, then check for odd noise, it wont take more than 30 minutes.
