so im finally doing the first upgrade to my 98 integra gsr and have been researching around for a full exhaust system. now i haven't found a header yet(any recommend are welcome ) but might be leaning toward the tri y header on ht sponsor marketplace but i notice most header has a o2 sensor bung(which is the one for before the cat) So does anyone know if the ws2 cat back has a bung on it also( for the o2 sensor after the cat) or does one need to be weld on? also anyone know where i can find a high flow cat? im trying to do bolt on without having the check engine light going on so no test pipe.

 

??? The second O2 is at the tail end of the cat itself is it not?

 

it is

 

That's what I thought. Someone needs to crawl their *** under their car once in a while.

 

haha i see. it to cold to be doing anything that y im tryin to get ready since the warm weather is coming. so is there any aftermarket high flow cat with the o2 sensor bung or one need to be weld on? can it even be weld on a cat?

 

Maybe you missed the part where we said that the O2 bung is ON the cat? Stop being lazy and do some window/comparison shopping. Start with Ebay.

Unless you got this car yesterday, you should be ashamed that you know so little about what's already on it.

 

and i think u miss the part where i said is there any aftermarket cat with the bung on it? and yes i did just recently got the car during the winter but ty for that info ill just call the spot and ask when i decide to purchase one since u obviously like being a smartass

 

I think YOU missed the part where I said go window shopping and compare cats. If you had you might have seen something like this.
