WTB: 6th gen civic 2.5" upper charge pipe
 

I need an upper charge pipe for my civic. I ordered a cheap cai off of ebay and they promised 2.5" but it measures 2.75". I wouldn just rather have a plain old 2.5" upper charge pipe.

you can just use a 2.5in coupler and make it fit, or you can get a reducer instead of buying another pipe.

Or you could always just get your $ back and get another CAI.
