cams with oem cats

[Clipboard]

Really want lope in my car and I enjoy the exhaust note where I have it with my oem cats. With limiters and a good tune will stage 3 comp cams be able to provide that safely? I understand the cats will be a choking point.
My cats are paired to kooks super street headers and down the road next year I'm looking to put a tvs on the car also.

Should hold up with a solid tune.

No problems. I'm running stock cats and have run them with other combos including Hot Rods. Still on the original cats. My own opinion is that as long as the tuner doesn't disable the rear o2 sensors and cat protection you should be ok with any setup.

Thanks guys! some have said that limiters for the coyotes won't produce the "cammed" sound, would I being forced to get lockouts and time the cams?
