Sup dudes. I just put a 99b16a2 in my 94hatch, I'm using an aftermarket gsr header, and I found out that my old d16z6 catalytic converter is too long to fit, its about 3inches too long. Do you guys know any stock cats to use from any oem honda/acura that'll fit?

 

I would suggest changing your exhaust setup to accommodate the cat rather than change your cat.

 

have the exhaust modified to fit the stock cat.

 

As stated you'll need to modify the exhaust. Cut the first 3 inches off the intermediate pipe (measure first for an exact measurement, i'm just saying 3 inches because thats what you seem to think its off by) Re-weld the flange back on and bolt everything back up.
