I wanted to get the DC sports 4-2-1 ceramic headers for my LX, however on the web site for the reseller it stated that the 98-99 DC header will not fit the LX/SE Accord with the 3 bolt converter flange. Do they mean the catalytic converter flange? I looked up the Honda parts listing and all the 4 cyl 99 models use a 3 bolt converter flange. Has any one installed this on their LX? If so, any problems? Thanks.
