i was wonderig if a hi flow cat from a gsr would fit and ls from the same gen. i thought it would, but im still unsure...anyone?

If you're talking about G3 Integras, it will only fit a '00-'01 GS-R without modification.

True Story.

Yeah, but what header and exhaust was on the GS-R? Doesn't matter what car it came off of, as long as it's the right length you need and has the right number of O2 bungs.

So find out what you need and if it's what you need.

basically, my problem is this...i have a '96 LS integra turbo and i am thinkin about runnin a high flow cat, but most of the ones made for an LS that i found are 2.25" diameter. i want something bigger, so i was just wondering which cat might fit thats a little larger?

Just get a catco cat

what is a good brand for a high flow cat?

1994-1999 GS-R have a 17.5" cat with 2 O2 sensor bungs. Measure the cat you have on there right now and see if it matches. You may need to plug 1 or both of the bungs. Running OBD1 - plug both, your primary O2 is located in the A-pipe. Running OBD2 - plug the one upstream of the cat, install your secondary O2 downstream of the cat.

A M18X1.5 screw will work, I found a M18x1.5 oil drain plug at the auto store that worked.
