Is this straight pipe or what exhaust is this? (youtube link)
I’m considering buying this Corvette and the dealer only mentioned it has an aftermarket exhaust, but doesn’t have much detail on the setup.
Video of car idling and a few light revs:
I’ve tried asking the dealer, but they don’t really know much, so I figured I’d ask here since I know people on the forum are much better at identifying setups by sound.
From what you hear, does this sound like just an axle-back/muffler swap, or something more like a full cat-back system? And is there any indication of headers or removed/changed catalytic converters?
Asking because of emissions.

I guess it doesn't matter a whole lot whether it has a full cat-back system or just the axle-back. Just need to somehow know whether it has aftermarket headers or removed cats, just things that would mess with emissions. Would you be able to see this by looking underneath the car?

Like NORTY wrote...you need to get it on a lift. Aftermarket headers will be obvious compared to OEM headers. The OEM catalyst converters may or may not be in place. Again, it will be fairly easy to tell if they are in place or replaced with after market converters. As long as something is in place, you should be OK from an emissions standpoint. If none at all, that may be a problem depending upon regulations in Norway.

Appreciate the response. I asked him to put it on a lift. Here's the video from underneath the car: https://youtu.be/ptiIJO5_7-o
Are you able to see the catalytic converters or headers from underneath here?
