2008 corvette performance exhaust and 2.73 axle ratio by stuntmansteve

I am going to order a base model 2008 corvette and I am trying to determine if I should get the performance exhaust system and the 2.73 axle ratio. Any advice would be appreciated.

I ordered a base model with the performance axle. I have read in magazine articles it does make a noticeable increase in mid-range power. Also, the 2008 has a quicker shifting automatic. I passed on the exhaust because of cost to horsepower ratio. It adds 6 horsepower. I haven't driven one with the performance exhaust, but read it sounds real nice when you step on it. Hmmm, maybe I should have gone for it.

I opted for the dual mode exhaust in my '08 and happy I did so.
I had an after market exhaust on my '03 Z06 which barked pretty good but at crusiing speed there was a "drone" which was a bit annoying.
The stock exhaust on the coupes was just OK...too mild for me but an after market cat back exhaust is about $1,500+ and you may again end up with the "drone" at cruising so the $1,200 cost for the dual mode made it a no brainer for me. Certainly not worth the $$$ for only 6 horses but I wanted it for a more aggressive sound. The drawback here is that the valves open at about 3,500 rpm and unless you are tracking the car, one would not get to hear the open valve sound very often.
Now, all one has to do to keep the valves open at all times is to pull the fuse for the dual mode (it's a stand alone fuse). Sweet music but the dreaded drone at cruising could wear on you.
SOLUTION--and this is awesome. There is a vendor who sells a "MILD TO WILD" unit which is ultra slick. $100 gets you the unit. It plugs into the dual mode fuse (a 2 minute install) and comes with a FOB so with a push of a button you can either leave them in the stock position or open the valves at anytime. It's a small FOB so I did the velcro bit and put it right next to the start button so I can open/close the valves at any time. The best of both worlds to me.

I wish I could of talk to you first. That sounds like a excellent set up. My car will be in Monday or Tuesday, so it's too late.

I read in my Corvette magazine today that the six speed auto starts the car off in 2nd. gear from a normal start, not in 1st. Has anyone else ever heard this before.

That's true, but you can over ride this feature.
Here's the deal...If you put the gear selector in "D", it shifts just like a regualar auto does...i.e., starts in 1st gear, up thru 6th.
Put the selector in "S" WITHOUT TOUCHING THE PADDLES and it operates like the regular auto with firmer shifts.
Activate the paddles and it will start out in 2nd but a flip of the paddles and you can put it in 1st.
More confusing than it needs to be but it becomes second nature after you have driven it a bit. A peek at the HUD shows what gear you are in. Easy to get used to.

Which vender did you get the "milder to wilder" exhaust override switch from. I funny thing happen to my 08. When it came in, the targa roof didn't fit right. On further inspection from the dealer (removing the rubber seal) that goes around the back where the targa roof hooks in, was a crack and damage. The engineers looked at the pictures the dealer sent and decided the car would be sent to a body shop, fixed, and sold as new. Well, I'm not buying it. So, I'm ordering another one from a different dealer, and getting the performance exhaust. Another bit of info. My car had a build date of September 24th, the day of the strike. The dealer checked with salaried management not on strike and confirmed my car was somewhere on the line that day. I sure hope the assemblers are happy with their new contract and build my second 08 a little better.

My wife and I have both been lately stopped for 7 or 8 over the limit, both were warned only, so we're not going to be pushing it much in the future.
