hey guys...im thinking about getting this race pipe for my 88 NA....but i was wondering...it said that the actuators would operate normally...how? the s4 actuators are opened by the air pump which gets the back pressure from the cats was it?

 

I think it gets its backpressure from the silencer they put on that pipe.

 

Ive heard Bonez stuff was crap...anyone back that up or deny it?

 

I have their superflow cat system, I think its awesome. I would recommend Bonez stuff to anyone, just my opinion though. Seems to be very high quality.
