X-Pipe modification with stock exhaust

[mfiver]

I'm very interested in the X-Pipe modification with my stock 4.4 exhaust.

I was hoping to find a sound clip but the link on the Home Page (http://s17.photobucket.com/albums/b8...n=view&current
=Mov_1228_002.flv) doesn't seem to be working.

For those who have done it I have a few questions please.

- In rough terms, how much does this increase the sound? i.e. 5%, 10%, 20%, etc.
-Is the sound increase mostly noticible outside the vehicle, or can you notice it much inside the cabin as well?
- Did you pick up any droning or resonance on the highway?

Thanks to all!
