Question about s4 aux ports and cat.
Question about s4 aux ports and cat.
Alright so I want to gut my cat this weekend but im unsure if there will be enough backpressure to run the aux ports or if I will have to wire them open. Just need a little input, thanks. (s4 na, of coarse)
As long as the split air pipe is connected to the port on the cat they will be operational. It's when you take off the split air pipe on S4's that you will run into problems....
