Well, I've been thinking about doing a full Bassani system on my '04 Mach, but I've heard the horror stories regarding the 4V header installs. In the expert opinions of those whom have done it, can it be done by someone in their garage? I am not a pro, my experience is limited to cat-back swaps, top-and-front engine mods, suspension upgrades (LCAs, Sway bars, etc.) and other medium-level mod work. Any help would be appreciated.
