so im gonna port out my exhaust header and o2 housing because i have to. to pass emmissions.... i got it tested and they said it was because i have so much carbon build up in my exhaust and that my o2 sensor is shot.
what parts of my turbo can i port???? because i want to port that too.
besides how much hp does porting your exhaust add??? its on an all stock engine too.
