I just recieved my 3" ac friendly dp. I had a flange I bought way back to fit my sc61. I notice my flange that I have is bigger opening than the flange that came on the DP...which you can see in the pic. I have a sc61 .63 ar would keeping it that small cause a loss of power? What would happen if it doesnt?? One more question I never got my bung welded up top by the flange for wideband. Is that need for tuning with hondata?? Thank you

is everyone going to look. I just need some simple help

 

it may cause a slight loss, but i wouldnt wory. as far as the 02, your stock one gets unscrewed and a wideband is put in its place. or at the dyno they have a separate one that goes in your tailpipe.

You can only use the WB in place of the stock sensor if your WB controller has a narrowband emulator. Some do, some don't. In any case, only some dyno's use the "sniffer", others use a wideband. I would weld in another O2 sensor boss anyway, since you are having to do fabrication to complete the downpipe.

 

I flared mine out to the side of the turbo's exducer.
