I want more sound but if droon is a problem then I can control it when on the highway

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.

I did not see any track gain with them so far - but we had an unusually cold day at the track Saturday (negative 230 DA and 53 degrees and 70% humidity) and I could not get any grip at the line, spinning every time.

I did notice on my HP Tuners logs at the strip I was running lean so I added some fuel, but I can't say if that was because the cutouts or the cold weather but I will find out soon. We don't stay cool long.

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.
