heads back...
 

purchesing some heads on back because... well i need to. current heads are loose and stock and.... yeah. ive read some exhaust setup arguments just now but im still curious...

BBK shortie heads
o/r xpipe
flowmaster 40's

planning to fabracate removable cats.

any suggestions/things im missing? ive never replaced headers back but i want to (i love my mustang!) anything i should need to know?


is the difference in the above that the inlet tube is off to one side? would i need an O/C and a C/O or does it matter?


thanks in advance for the learning of a n00b to exhausts.
