I'm wanting to put the whole 98 ls stock header, catylatic and exhaust pipe so I can pass emission on my 98 gsr. so my question is will it fit and pass emission?

 

If it's the whole exhaust system, yes it will fit. If you tried to mix and match you'd run into problems because the 94-99 GSR headers and cats differ in length from other Integras. 00-01 GSRs were the same length as the others.

 

just as madmax94 said, if it's the whole exhaust system header, cat and catback then it'll work.

if you try to just use the header it'll be too long.

 

Y wouldn't u pass with the stock gsr?

 

No I fail emission cause I'm running too rich I'm at over 2000 when it should be below 400 or something. And they guy said it's my catylatic that needs to be replace. So I have a entire ls exhaust at home so I figure I'd swap it if it fits. And also one question does the 02 sensor that sits right in front of my catylatic read the same if I put it at the end of my header cause that's where the ls had there's.
