Here is a video of a cammed 4.6 with an o/r x pipe and a SLP catback. I must warn you, it is ear shaking loud, especially when he takes off down the road. Please right click and save to your computer.

After watching this vid, my delima is now do I want the all out loundess of the SLP (accompanied by the sloppiness of the SLP) or do I want the loud as hell, but clean, sound of the MAC catback. I am really torn between the two.
