    Have gotten a few answers to some of the questions asked.

    There ARE engine intakes in both side scoops.

    To change the air filter you need to remove the two top latches on the front of the trunk (8 torx, it looks like) then unscrew the 4 cargo net fittings (by hand). Then lift out the front of the trunk liner. Then 16 fasteners to open the airbox.

    The exhaust tips are the same npp or not.

    Only ONE oil drain plug.

    Couldn't get a firm answer about base exhaust vs stealth mode, but one GM engineer driving a base 1LT w/o npp said its quieter than the C7 base exhaust.

          Id recommend the npp exhaust..its awesome to have the option...sometimes loud and roaring...sometimes stealth for highway cruising..

          aftermarket exhausts can drone on the highway and that can be tiring after the first hour or two.

          npp is a nice option...

          i ve had corsa indys on my c5 z51 and sounds great but could be tiring on the highway. I did cam headers and gears on my z06 but lept the titanium exhaust...and I did the stock exhaust with NPP and I found it the best over the past 135k miles...

          quiet or relatively quiet when you want it to be and then as you rev past around 3500 rpm it opens up and roars...

          corvette engineers are awesome.

            I guess with motor oil being scavenged from three places in the dry sump engine instead of just one, there isn't enough oil left in the engine sump at any point in time to make it worthwhile to have an engine oil drain plug.

              Can we remove the catalytic converters for some added sound?

                I doubt it, at least not without some electronics reprogramming. The C7 has 2 cats in each bank. You can remove the rear ones without any issues, but the front ones are monitored by the O2 sensors, and removing them will throw a code

                The C8 appears to have only 1 cat per side, so removing it would certainly throw a code.

                  No
                  There is 4 O2 sensors and worse with C8 LT2 is 2 of them are built into the CATs and 2 are in the mid length headers
                  Taking CATs out and the PCM being locked means no way to turn off any of the DTC (error codes) related to the CATS and 02 sensors
                  O2s would also not properly report the exhaust makeup so PCM would commad the AFR incorrectly

                  As large as those CATs are I doubt they would effect the exhaust sound much

                    While talking to an engineer today, was told the engine has to be dropped to remove the valve covers due to oil tank limiting clearance. Maybe the aftermarket will come up with a cover for us that want a different look without a major install.

                    The front area where the plate goes does in fact remove (first person I asked wasn't sure, thought it might mount on surface.

                    The engine lights only work when you open the hatch or doors (no on off switch) but is a plug in so they can be changed to other colors. I failed to ask if the plug is on models w/d appearance kit. If someone could ask it would be appreciated as we're headed home.
