has anyone used this rb header
i was looking on the rb website saw the road racing header with o2 sensor and 6th port aux. and it sounds good to me. if anyone is using it how well does it open the 5/6ports.
im more than likely going to get this after i get my idle down from 1500 and put a custom exhaust because the full setup is too much money for an exhaust

The amount of pressure the header has to open the intake ports on an S4 is based on the amount of restriction in your exhaust system. The more backpressure the more pressure to open the ports.
If you have a problem you can use the airhorn mod or you can use the electronic ports.
Idle that ***** overrated
