Hey this is prob a dumb question and i tried to searchin it on here but the h-t search is being gay. I have a 94 hatch with a gsr swap and im goin to purchase a high flow cat. would i get one for a 94 civic or an integra? are they the same size?

integra. i just got a universal from magnaflow and had the local shop weld it in.....works great.

You could also go the extra mile and have flanges welded on so you could bolt / unbolt the cat to swap back the stock one when it's emissions time. (if emissions are an issue in your area of course) I don't think Mariland* (spelling?) is too strict about that though.

^ this is a good idea too
