Rick, a few questions.
1. you want it for bling bling?
2. sound?
3. Balls out performance.

Stock factory exhaust is 2 7/8" why go smaller pipe.

I would do is 2" primary headers, 3" exhaust w/X-pipe Dynomax mufflers one 3" inlet/ two 2 1/2" outlets buy yourself some C6 ZO6 mufflers,use the flappers in one outlet pipe on your Dynomax mufflers, you can use the ZO6 tips, now you have a quiet exhaust and all out performance.

Trust me you will not loose any low end torque.

The reason most tuners suggest Corsa is because most corvette guys are old and anal they don't care for power they want bling bling and sound.
BORLA is proof of this.

PS
If you don't like the above exhaust i'm almost certain someone will buy it from you and then you can go buy your "grumpy old man exhaust"LOL
