i want to build an X-pipe for my charger.
what is the common angle [if there is one] on most available "pre-built" units ?
30 degrees or so ? 45 ? all are different ? [can't be that much difference can there ?]
the headers have a very short, 3 1/2" collector. should i go 3 1/2" to the X, then 3" from there, or 3" right from the collector ?
TIA !
