im thinking of getting it but it says on their page that to use it with the stock main cat it requires some slight modification. i was going to call today but i didnt get a chance untill 3:14 pacific time so they were already closed. what exactly needs to be modified to use it with the stock main cat? im thinking about going with the hks dp if its not really simple, but im kinda short on cash right now so if it is then the rx7store dp is considerably less expensive.

Its the alignment to the studs on the main cat. You can make it fit, just remove the hooks off of the rubber hangers and connect the main cat to the DP. Then just TIGHTLY fit the hangers back on. IMO, you should just get the combo. It's cheaper buying both than one at a time. Then later once you get a boost controller or aftermarket ecu, you can mount the midpipe on. Everything should fit if the combo is on there together, but for now, just put the dp on and do the tight fitment. Just giving my 2 cents on the combo bargain.

yeah id like to but id probably never use the mid pipe since id like the car still to pass smog, ive got a smog guy i use who doesnt really care about stuff like downpipes or things like that so that is no problem.

I have their combo, but don't use the mid pipe. I didn't have to make any modifications. It lined/bolted right up to the factory cat. Other then that, how the pipe attaches to the flange makes it a PITA to bolt up to the turbo, but for the price, its not that big of a hassle.

i bought the Downpipe before they started selling it as a combo, wasnt told that it was ment to fit up to their midpipe, i spent a whole day trying to get it to line up with the stock cat, then gave up
