500.00 bucks to spend....HELP!
I have 2006 z51 with only a CAI and canned 93 tune. I have 500.00 to buy some bolt on!
what will give me more bang for my bucks.
Corvette Mass Air Flow Sensor, LS2, Granatelli, 2005-2006
•Provides Up To 23 RWHP
•Bolt-On Installation
•For Use With Stock Air Filters
or
Holley #510-112-576
90mm Throttle Body LS-1/LS-2
or
RX Performance CNC Spiral Ported Throttle Body (GM LS2 & LS7)
Starting at: $165.00
Unequaled in performance gains and throttle response as well as improved driveability, these CNC spiral ported throttle bodies are the ultimate in computer aided technology that makes all hand ported units a thing of the past. Average gains of 12-16 RWHP. NO tuning needed but even more performance may be gained with good tuning
Tell me what to buy......

Message deleted, I didn't read the post correctly the first time.
I would put NOTHING that says Granatelli on my Corvette.

OP: I would save it and buy a FAST and get a dyno tune later on. The FAST is great for the LS2. Here is a thread that I made - http://forums.corvetteforum.com/c6-t...st-intake.html Good Luck!

Only bad thing is they are illegal in some states. You have to check.

Had QTP cutouts installed by Florida Performance in Fort Lauderdale. Overall very pleased with the job Rob, the shop owner, did. This was his first C6 and he found a great place to put them and made the custom mandrel bent Y-pipes to maximize flow from the cutouts. We found no way to put them right after the collectors but they fit well by the trans. I have the DTE brace too but it wasn't in the way.
Installed the wiring myself along the drivers side rocker panel, behind seat then out the wheel well under the carpet. Removed the rear inner fender and drilled a small hole in the wheel well then ran the wire down to the cutouts. Hardest part is finding a hot wire when the ignition is on on these C6's. I ended up tapping the seat heater fuse as others here have done.
They are loud and DEEP when open at idle. I've actually heard louder exhaust though, I was kind of surprised they are not louder. I think it is because of the turn downs and the fact that I have cats and the pipes are pretty long before the cutouts. On the track they have a nice race car sound - I'd say like Borla Stingers plus 25%. When you open them at a stoplight you will turn heads, that's for sure.
Overall happy with the mod, it gives me quiet during my morning drive but loud when I'm at the track which is what I wanted.
Here is a video of idle with cutouts open and closed. The gain on the mike makes the closed sound much louder than it is, it's really quiet with factory mufflers even with my cam.
Here are some pics:

I agree with saving a couple hundred more and getting a Fast, your stock Intake is worth $200 + in the fore sale section allowing you to recoup a few dollars. A professional tune is required.
The cut-outs will add a little power and sound awesome, fun mod as well for sure!

and have a used FAST90 if you're interested. You won't find a better bang for your buck especially in the mid-range.
