Modification to Down pipe to fit stock cat.

What modifications need to be made to the rx7 store downpipe in order to fit the stock cat? I have heard you use a dremmel tool but what gets dremmelled? The website states that some is necessary so what do they recommend? I know that an HKS or M@ wouldn't require any mod so I should buy one of those but I am already going to get the RX7 store one. Thanks.

you have to increase the diameter of the holes and (iirc) widen them further outward. i thought it was just the ebay ones that had that problem....

A quality downpipe should not need ANY modifications.

I was told that the one o bought used was from the RX7 store. I diddnt have to modify anything and it bolted right up. Nice quality piece.

I had one where the flange was bent and the holes were spaced a little wrong. Obviously I could have opened up the hole with a dremel, but you can't fix a bent flange without risking a cracked weld.
