Those don't look rusty as much as needing a little clean up.
FYI, if the add is correct those are off of a Z06 so those pipes are 3" diameter. If you have a regular or GS Corvette your pipes would be 2.5". Nothing a muffler shop couldn't make work though.

The ad doesn't say they're off of a Z06. The ad for the NPP mufflers says 05-13 LS2 LS3. Granted that some other parts, the ad says they're off of a Z06.
You dont think they look kinda rusty? I just looked at my base exhaust from a 2012 and they really do look brand new, no rust at all.
You and I live in N. Texas...we don't see much surface rust here. Like the above poster said...they just need to be cleaned up a bit...that isn't a serious, pitted rust issue from what I can tell.
Bottom of the add page (scroll down) calls then out as 3" NPP Z06 mufflers,
And truth be told, kind of high in price and shipping, since you should be able to find then a lot lower through Craigslist in your area instead.
As for fitting your later model C-6 non Zo6, will need to have the axle over section pipes rework for the needed bends, and pipe reduction down to 2-1/2" as well.
This is not the same ad the OP posted, you clicked on another link on that page.....
The ad specifically says they came off a GS and have the 2.5 inch pipes.
Let me know if you need any help installing these when they come in. I am local and just recently installed 3" Z06 NPP's on my GS with LT's. There is definitely a trick to getting them to twist just the right way to get through the hole over the axle

Thank you! I love this forum, you guys are awesome!
Z06's don't have an NPP exhaust. They have duel mode and do not have the holes. They are also 3 inch not 2.5 although the do narrow to 2.5 at the can's.
This is from the AD... Up for auction is a nearly new set of genuine General Motors Corvette C6 NPP Dual Mode exhaust mufflers - less than 5,000 miles on them. They came off of a 2013 LS3 6.2 Liter (430 HP) motor with the NPP exhaust option that adds another 6 HP. All pieces have their General Motors embossed or engraved factory numbers or stickers. All parts are in very good condition with no dents - possibly some light normal road use scratches, etc. Really good condition as you can see.
These mufflers will fit stock 2005 thru 2013 Corvettes or the Corvette Grand Sport. Will not fit the Z06 & the ZR1 as they have 3" piping.
This set have 2 1/2" piping. 3.5 inches per tip.

order the sunset orange creations controller... you'll be very pleased.. also, order a vacuum ball from autozone and insert that into the line right before the controller and it will keep the valves closed under light constant throttle like factory.
With that controller i mentioned (it's more expensive) you can keep the exhaust completely closed in the "closed" mode. you can program the rpm opening and closing of the valves with it through the DIC as well. it also has the full open mode..
all of that you can control with the door lock button..
you will love the NPP... i also installed a late model (2012) NPP came off of a '12 GS with 5k miles on it.. what a score. paid $350 with the catted mid section as well.
if that add is right and they are off a 2008, keep in mind the bend at the crossover is at a slightly different angle than 2009+
you will need exhaust work they are not a direct fit for any exhaust post 2008 (e.g. 2009, 10, 11, 12, 13)
