I am thinking about going with a set of long tube headers on my 2017 Grand Sport and wonder if i can just have my stock mid pipe modified to fit? Has anyone done this and is it just not feasible to get the performance out of it?

Shouldn't be any reason the mid pipe can't be cut and modified but my question would be why the headers? If you are looking for more HP, that's an expensive setup to gain only 30 or so whp. If you want HP, spend the extra and do a camshaft mod and tune as well. Those mods will put you close to 500 whp.
Otherwise, give one of the area Corvette performance shops a call and see what they recommend.

I changed my headers to ARH and did a Borla mid pipe and B&B exhaust. If you're going to have better exhaust might as well have a better air intake as well. I would go with a Halltech. Did a few other small mods, dyno showing 530 at the crank., 2015 C7 M7.
You did an engine dyno or mathed the numbers from rear wheel?
I cut my secondary cats out and welded in straight pipe... very easy to do and also got $70 for the cats... sounds a bit throatier....cheaper than x-pipe..
The dyno showed 530 at he crank. Rear wheels on the roller.

I managed to find a set of long tube Kooks headers and they were brand new still in the box on market place and they were less that half the price of a new set so that was cool. Being the flange section that connects to the mid pipe was a bell type shape I found at a discount in Quebec with free shipping a mid pipe to match so going in that direction. I have the headers cerakoted now so going to get them installed soon as I put road insurance on the car and put it on the road.
