Need an 11 second C6
I plan to purchase a C6 and I'm leaning toward a 2011-2013 Grand Sport A6. I love the wide body look of the Z06. I had a 2000 Camaro SS for a while and had it running 12.0 before I sold it. I need the vette to be faster than that and I'm curious to know if headers, X-pipe and CAI will get me there. Will a stall converter have the same impact that it did on the A4 Camaro? The Yank 3600 was by far the best mod I did with the Camaro. It seem that with the vette having an A6, the stall won't have quite the impact because the A6 already has a lower 1st gear.
I will consider SC also. I'm a DIY'er and installed headers, duals, LS6 intake etc on the Camaro. The vette will be a cruiser and I will rarely go to the drag strip. No interest in tracking the car either. I want to be able to take the car on trips, etc. Reliability and ease of maintenance is important also.
Thoughts? Am I asking too much?

with the CAI, Long tube headers Xpipe and catback of your choice and tune alone will get you in the 11's the stall depending on which speed will just get you close to the 10s now of course you need a sticky tire to do it but seeing that you owned an Fbody before then you know the drill already good luck

2021 C6 of the Year Finalist - Modified
I have been through this **** before ..... You are not going to get that car into the high 11s until you get your 60' time way down ... and to do that, your going to need to put a set of drag radials on the rear, and if your C6 has an auto transmission, you really need to change out the stock 1,600 stall converter to a good quality 2,800 - 3,000 stall converter.
Bottom line ... your C6 needs to launch real hard ...
Enjoy .

An 11 sec 1/4 mile is not easy with an LS3 that is not supercharger unless you throw a bunch of money at the engine.
Sure, it can be done with nitrous ... but is that the way you want to achieve it ?

yea dont need that catback my bad i was thinking Fbodys for a second lol anyway yea just headers, X-pipe and tune with DRs will get you or should get you into the 11's the Converter will get you deep look at the Yank PAS 3400-3800 or Circle D in the same stall speeds the CAI of choice seems to be either the Vararam or Halltech then all the others fall in line its basically pick your poisen but make sure you start out with the 275/40/17 DRs i went bigger only because i borrowed mine from my Fbody WS6 it hooked but a little to big got myself some 315/35/17 MT DRs just need the wheels and back to the track i go looking for 7.4-7.5s stock stall already went 7.8@93 but with a 305/35/18 MT DR

I appreciate the responses. It's starting to feel like a later model C6 Z06 might be the easiest way. 
I can hold my own with the M6 but my concern with a Z06 is how long it takes to warm up due to dry sump. I believe I'd have more money into a GS if I add a SC. I do kind of prefer an auto trans. I've been shifting gear for 30 years and my DD(1st gen Tacoma) is a MT.

I went 12.22@117 in my 2012 base coupe A6. 1.986 60’ time and tires did spin. Lousy track prep too. Only had a canned Diablo tune. If I could have knocked a tenth off of the short time I could have squeezed out an 11. My last car was a 99 Z28 with small cam, headers, yank SS3600 and 3.73 gears. Ran 11.88@118. Good luck.

A Yank converter would also help quite a bit but with that you'd absolutely need to be running drag radials.

C6 of Year Finalist (performance mods) 2019
11's are fairly easy, with a minimum expense and labor. I ran 11.89 with a Vararam CAI, Hoosier 275 DR's, Z06 manifolds/H-pipe/mufflers, and tune. I swapped from the OEM converter to a Yank 3200 and ran a 11.60 the following week with no other changes.
I later went to a 3600 Yank and continued to tweak the tune and other small details. Found some really good air and went 10.82.
I even went 11.44 on street tires while having some fun during a road trip to FL. The only prep was leaving the luggage in the hotel room before I went out to play.
You don't need a SC, cam, headers, or even a higher stall converter. The real key is the tune. You gotta be willing to understand/learn how to tweak it yourself.

WOW, I have gone from slightly discouraged to mostly encouraged from a wide range of answers. I'm not afraid of wrenching. I keep being drawn toward a GS even when considering a Z06. I really enjoyed the 00' Camaro SS I had but I believe the C6 GS will be even more enjoyable. In its stock formations(with DR's) it will be close to the modded Camaro I had. I suspect the GS would be quicker than my old Camaro once cars are off the line(the Camaro pulled a 1.66 60'). The Camaro dynoed 360hp/364tq.
I really, really appreciate all of the responses.
Good to hear.
WOW, that's impressive. Is there an advantage to Z06 manifolds/H pipe vs headers/X-pipe? I loved the Yank SS3600 I installed in the F-body.

Sticky tires, a tune and some decent air will easily get you into the high 11s as my friend has a 2010 has that setup. I don't think he's turned off transmission torque management in the tune however but by doing that he'd pick up another 2-3 tenths.
A Yank converter would also help quite a bit but with that you'd absolutely need to be running drag radials.
