got it up on the jack today, seems its definitely the catS .. yeah, both of them. dropped the h-pipe, and apparently the rear half of the material broke off in the back and is bouncing around inside the cat. calling BBK today, trying to get new h-pipe, if not ... then dummy-cat it is. just beat out the internals and weld a pipe through it

(cats) what are these?

are they needed and if so for what




Oh wait I get it J/K I passed the E-test withouut my cats and with long tubes and dumped muffs but it all depends on which test they do by you
