serge, I suggest you check out these two threads. They include many more details including video clips so that you can hear how my car sounds for yourself.
This thread covers the installation of the exhaust and HFCs that Sharif is talking about

I have since installed a new intake, and just yesterday I got more dyno results and made another video. All of this is detailed here:
Install of Stillen G3 Intakes complete - review, etc.
You might also want to check out my journal thread, where I document all the things I've done in a single thread:
