Default double x-pipe Grand Sport

My quest to change the tone of the exhaust had brought me to this:

This is just a rough fitting without the welds. We've used Magnaflow tru xpipe in conjunction with the original GS xpipe.

I don't know the dyno results nor do I care about those. I needed to eliminate a certain drone from the cabin and I needed some more exotic sound. The sound now is much smoother and I do have a tendency to push the car harder. My dyno-butt is happy. Overall feel of the car is more solid. Next we will be working on adding some bypass pipes to increase the high frequency note. My cost so far is : $50 for a xpipe from Ebay[ new but a resale] , 150 bucks to weld it in.

Increase the high pitched sound the Corvette is already plagued with?

No thanks.

Good luck in getting what you're after though.

Floyd, this has nothing to do with increasing any squicks. It is just tuning the exhaust to obtain a better defined NOTE [ like a musical tone]. The reason the other exotics sound so "tight" is because their exhausts are accoustically fine tuned. A stock Corvette sounds like a boat, too much unwanted resonance. My quest is to make it solid and precise. To obtain this effect you can perhaps find another exhaust or you can play with your own pipe [ no pun intended]. It is a lenthy process, trial and error. At some point you end up with an exhaust that has the unwelcomed vibrations wheeded out and you like how it sounds.From this point it's time to adjust the VOLUME of it to your liking by reducing certain baffles in the mufflers. Of course it's all a personal preference, some people like the boat sound and it's nothing wrong with it.
I'm going to Europe for 6 weeks but I will post the sound video when I come back. Peace, Greg.

Corsa recently introduced this concept for the C7...wonder if it really works (i.e. 5 rwhp?)and could be applied with Magnaflow shorty headers to a C6.

The flatplane crank on other exotics has a lot to do with how "tight" it sounds.

why exotics sound that way is 180 vs 90 exhaust.

I am more interested in the performance aspect versus the sound?
