Sup fellas. Need your help. The current setup I have is a 2.25 custom catback with muffler but the shit is starting to rust. Also I think the honeycomb in my cat has broken off because my exhaust sounds really muffled and the same thing happened to my boy. I am looking at 2.5 high flow cat, with 2.5 piping and muffler (More then likely all coming from kteller). Stil can deciede if I want dual tip or oval muffler.
I am still runnging the stock f22b1 header which is 4-2-1 design. I looked under the car and I see that the cat is 2 flange bolt in/out but what side would I have to get for the header side? Would I need to get the 2.25 to 2.5 high flow cat or should i get one of those collectors along with it? Pretty soon the turbo kit or h22 swap is going in so that is why I am going with a larger exhaust.
