I searched and couldn't find what I was looking for. I'm looking for the stock cat for my 01 ITR. Someone I know has a cat but it's off of a 1997 GSR. I need someone to help me find out on here if the cat's are compatable.

Part numbers:

'97 GSR: 18163P75A11
'01 ITR: 18163P75A10

The numbers are off my the last number in the part number. Will the GSR cat bolt on to the stock ITR?

 

Anyone?

 

measure it, it should be about 17" long..

 

It's not the lenght of I'm questioning, I just don't know if it will bolt on..

 

i think about what BoS DC2 is getting at is to measure the two cats. if the lengths differ than your answer is no it is not bolt on.

 

1997 Integra GSR has two o2 sensor bungs.. 2000-2001 Integra GSR is more likely to work as it only has one rear o2 sensor bung..


From left 2 right.. 1996-1999 Integra GSR oem cat, 1996-2001 Integra Ls oem cat, Carsound 96-01 GSR aftermarket Hiflow cat and last but not least 1996-2001 Integra Ls oem cat..

 

the 94-99 gsr's at different length headers from all the other integras. it just places the cat farther forward on the car. the mid-pipe is longer on them to compensate. they also have the primary o2 bung in the front of the cat, as where any other integra, the o2 bung is at the end of the header.
