i have a 92 honda civic cx with a d15b7 from a 94 dx in it and i was wondering if anyone has an idea on where to get flanges for like the one from the front of that catalytic converter ? or if thats even possible i want to make a test pipe to replace the cat because when i got the exhaust kit for my car the morons at the exhaust shop welded the flange on crooked to the catalytic converter and now it rattles against my shifter arm when im driving and its quite annoying any help or input is appreciated thanks oh and the flange on the back of the cat to the exhaust pipe is a 2 bolt flange to because they cut off the 3 bolt flange and put a 2 bolt on it becuase they were out of 3 bolt gaskets....... which made no sense but thats where the flange got welded on crooked
