First...and not to be a jerk... but what the heck do you mean by this "2005 SRT6 w/o turbo"??? You're on the right track wanting to upload a file for the noise, no one will likely be able to help based on the info you have provided thus far.

I personally like to take a video with my phone or tablet, upload it to youtube, and post a link here to the video. You'll obviously need a device capable of recording video and a youtube account for that!
