guess i'll find out tomorrow, finally yanking the cat to see if it's clogged or not.

 

so, yanked the cat and it was pretty dirty inside. partially clogged as well. so i tried the test pipe, and while it was a lot of fun revvin it up locally, i had no power and it idled like $hit. had a brand new bosal cat and installed that and she ran a lot smoother. pulled a code for an iacv as well, again.
