I have an intake, resonators (instead of cats, so basically test pipes), x pipe, mufflers, 2.5" piping, and am soon getting headers and a plenum spacer.

The reason I have those resonators is because the aftermarket cats I put on blew out, and so I think that may be because my mixture is off but I have no clue.

So... should I be worried given the mods I have and am going to soon have, and also with that happening to my cats? Is my AFR dangerously off?

if ur NA, dont worry. How did the X pipe change ur tone? Less rasp aswell?

Once you put all those breathing mods on I'd get an ECU flash at the least, or a UTEC and tuning at the most.

your AFR might barely be off but nothing to worry about, with those mods my AFR was 13.1-13.3 all the way across till 5000 and got richer....

just read up more and look at peoples dyno sheets and compare mods with their dyno graphs.

or simply buy a wideband so you know exactly what it is, there are plenty out there for around 300 that will tell you everything you need to know...

thanks guys, plumpzzz i dont know how it changed it because ive never had the exhaust on without the x pipe, but when i get the old blown out cats removed and the resonators installed im debating having them cut out the x pipe for a sec to see how it sounds, bc im curious but only if its really cheap to do and undo.
