the time has come for me to get a whole new exhaust system for my car. i got a muffler coming but need to get a new catalytic converter (old one rusted off). the one i am looking at is the Magnaflow 9400 universal fit with the 2.25" inlet and outlet. link is here: http://www.car-sound.com/universal/940.htm

its the first one pictured and has the 2.25" inlet and outlet. i know this is a universal fit one, but will it work on my 90 Integra GS coupe (referring to the overall size of it)? thanks for the info and help all!!

 

I would suggest going with a Carsound High Flow Cat. I have one and love it!

You said you were going to get a whole new exhaust system, so how big is the piping going to be? That will tell you the size you need for your cat..

 

its going to be 2.25" diameter exhaust pipe that i will be putting on the car. the link goes to a Magnaflow catalytic converter which is made by Carsound (i do belive...could be wrong tho).
