Im ******* stumped. I ordered the 2.5 inch bolt up system for my 99 DX. I also ordered the 2.5 greddy dp and a 2.5 test pipe. So, they all showed up. Here is the problem. The DP and test pipe are 2 bolt flange (like all civic exhaust componente), but the flange on the end pf the cat back is 3 bolt. I tried to get them to mate up well enough, but it was no go. Now I have this half *** setup that is sagging and l;eaking. Does anyone know how I can mate up the 2 bolt to the 3 bolt? Is there an adapter I can buy or fins that will allow me to hook these up?

Thanks.

AM bump. I looked online and couldnt find an adapter flange, so I could still use some suggestions.

 

the 3 bolt flange is made to bolt up to a catalytic converter.......

buy new flanges and hav them welded to the DP or where ever needed.
