Anyone know where I can buy a secondary cat delete? I have dps and would like to delete the secondaries as well but keep my stock muffler.

On non-comp F97's (Comps tend to be fine), I'm pretty sure running a set up like this, by keeping the stock muffler, has led to problems. Something to do with the pressure in the muffler snapping a piece or pieces off and then terrible rattling sounds following soon after.

That is, if I'm reading your ? correctly.

You may be able to find the subject in a forum search, or, if you have a Comp, you may be fine. Search 'cat, Dinan, rattle', cause I seem to remember people swapping out to the Dinan muffler in the thread (though that didn't go well at first either for some reason)

Good luck!
