I bought both stock cats and had a muffler shop cut them off and weld pipe instead I’ve installed the primary cat and am gonna do the secondary one this week, so far I have an injen intake, the downpipe, 3 inch straight pipe with a performance resonator and ktuner, my end goal is to make it turbo but I don’t know where to start

 

Good job on taking matters into your own hands instead of waiting around for someone to sell one. If you could provide some tutorial on it, I'm sure a lot of ilx owners with that engine would be very interested.
