I want to remove my cats and replace with a straight pipe, and then remove the airpump. I've seen where people say the air pump helps with 6 port actuators or something like that (in addition to moving air to the cats), and was wondering if I'd have that problem to deal with on a 1986 N/A.

 

air pump does them on the 89-91



just do what you want then wire your six ports open...

 

if you look theres a little vacuum line going from the back of the intake to the pipe that goes back to the exhaust, as long as you have that it'll work

you say 89-91...Mine's an 86...would I still need to do that?

 

nope, yours is different
