hey monkey, where the hell can i find a mugen header for a 4th gen? I tried once upon a time to look for one, but every place I found on the web which showed it in their stock told me they no longer carried it, help me out buddy.
Also, I would imagine there's a slight difference in strut tower bars for the front. There is the kind that just braces the two towers, then there is the type that does that, but also has two mounts for the area above the firewall, I would imagine if you want the stiffest possible, you'd go with the latter.
