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

 

is there ne good 2.5 higg flow out there?. i have an apexi gt header and i wanna go from 2.25(end of the mani) to 2.5 to the cat and i think my apexi n1 exhaust is 2.5 right?

 

i just installed mine on friday i got a ls in my coupe and wound up getting a uni and having a flange welded on it works out good and for anyone in new jersey apparently there strict on it whet thru today and failed emissions basterd cali emissions standards
