Cam and Cat Question

[G0S7]

Hey guys, I was just planning to put together my parts list but there's a couple questions I have still lingering that I haven't really seen asked or discussed, recently at least.

1. Are the stock cats so efficient that high-flow cats performance increase would be negligible even with tune and full bolt ons? Anyone run highflow cats and have CEL or leaning out issues before tuning?

2. Just curious, and for the sake of enjoyment, are there any choppy cams out there that are as plug and play as the OEM 392 cam? Meaning will not require higher stall torque converter upgraded pushrods and what not.

Thanks

For #2, FRP has a few cam options that fit that goal.

Thanks for the reference. I'm not too familiar with FRP but their MK82 cam has be interested!

I ran the wifes last 2 Challengers catless with no tune,just did the old school anti-foulers under the rear 02's,neither one threw any codes.I did have an A/Fr guage in her 2019,and it ran right around 14.4,cruising down the highway at 70mph and right around 12.6 to 12.8 at wot,which is about as good as you're going to get

The fact that I can get my truck tuned by the same shop that designed the aftermarket cam I decide to go with makes things even more appealing. I think this may be the way to go for me.
