X-pipe and down pipes
So, I’m about to purchase the Borla catless x-pipe (model #60547) and AFE catless connection pipes (I’m pretty sure they can be called down pipes too). That should get rid of all four cats, but I’m curious to know if anyone else has this setup. If so, could you post a video of it? I’m sure it’ll sound very aggressive, but I would like to get an idea on what it would be like compared to stock. I’m possibly going to be putting the AFE Power Pro 5R CAI on as well. Any insight on what you guys think this will sounds like and do
for my car would be great. Thank you!

#1) The Borla 60457 is no longer manufactured
#2) Technically speaking, down pipes are referencing the exhaust pipe exiting the hot side of a turbo charger. So no, I wouldn't call them down pipes.

2) insanely obnoxiously loud. Otherwise tone is very similar to stock, just sounds uncorked.

I have this exact setup on my Z06. No tune needed unless you're going to use a program to turn the CEL lights off. I just used the big daddies 90* sims. As for the intake, I'm not sure if the LT1 requires a tune. I don't see why you would need a tune for either the exhaust or intake on a LT1. I'm sure a tune would get the most out of the setup, but I don't see it being a requirement. On the LT4, I'm personally not comfortable putting an intake on without a tune.
I don't know about the sound difference between the LT1 and LT4 with this exhaust setup. It's definitely louder, but IMO not crazy loud. My friends say its really loud when I get on it, but I can't hear it because I'm in the car. I've actually been thinking about adding an axle-back. The nice part is when you put it in stealth mode its really quiet. I don't know if I want to lose that option.

Definitely, something to keep in your back pocket for down the road. You will definitely want Big Daddies Garage angled o2 sensor spacers to prevent a CEL.
