HOOOOLD EVERYTHING! Don't even THINK about a cat back!!
Yeah, you heard me right. Don't even THINK about buying a cat back exhaust, or ripping out your muffler, or ANYTHING like that until you've read this...
So ALLLL my life I've been wishing for the perfect exhaust. That is, one that is REDICULOUSLY loud when I want it to be, and one that makes minimal racket when I'm taking the president of the company to lunch. Historically, I've walked the line. 50-series flowmasters and the like - selling myself short on sound to maintain a reasonable "mature" image. And that's where I was originally headed for my new LS2 Trailblazer SS...
NO MORE!!!!!!
On a whim, I went to the local speed shop and picked up a 3-inch stainless cutout pipe, a motorized butterfly flange valve, and a digital controller. I wired up the whole shebang by taking out the console and drilling a hole just behind the emergency brake apparatus, and installing the digital controller in the glove box. I took the pipe to the local custom exhaust joint and they did a FANTASTIC job welding it between the y-pipe flange and the stock muffler - it JUST fit, and the whole thing is just as removable as a catback system would be). I took it home, hooked it all up and. Well....
It is FUU***KKKING INCREDIBLE!!!!
NOW, I can cruise quitely past the cops, the office, and the ex-wife's house! And when some jacka$$ in a new mustang pulls up alongside, I can RUPTURE HIS EARDRUMS!! The digital controller lets you set it full open, fully closed, or anywhere in between. It has presets. It has a digital display. It has.... the keys to my heart.
It is friggun AWESOME. I can honsestly say that had I known that in the past that this was such a viable option, I would have NEVER installed a cat back on my daily driver. This is the best of ALL worlds, and in case you hadn't noticed, I highly recommend it.

Wll duuuh....
I know I'm not the first, but this is the first exposure I've had to it. I bought the parts from QTP. The stainless 'y' and the 3" motorized valve were $200 in kit form. The digital controller was another $100, and the muffler shop charged me $100 to do a REALLY good job welding in the adapter.
The whole thing was less than a cat back, and is infinitely cooler... Sweet.

No no no...
The valve COMES WITH a two way momentary switch (like the one that operates the tops on convertibles). Push and hold it in one direction to open the valve, push and hold in the other to close it. The drawback is you have to hold the switch, and you run the risk of over-closing the valve and making it leak over time...
For an EXTRA $100, you can get a digital controller that you install IN LIEU OF the toggle. It self calibrates and knows exactly where full open and full closed are, and allows you to set presets anywhere in between based on a "percent open" setting. Mine is at 15% and 40%. It also had an "activation wire" that can do different things when you feed it a ground. So if you rig it to a throttle switch or a button on your shifter, you can hide the digital controller in your glove box (like I did) and operate the thing that way also.
Pretty cool...

Betcha mine sounds identical and all I did was spend a grand total of $9 on mine and it took me an hour to fabricate it and weld it in.
Yeah its nice opening and closing it from inside but all it takes me a whole 45 seconds to get on one knee, put the cap on, thread the nuts and tighten
Yeah, it looks ghetto but it doesn't sound ghetto and I couldn't justify spending that much if I'm going true duals anyway soon
Anyway, what matters is you're happy, is your y-pipe catted?

This is it - I'm not changing the exhaust any further. My level of backpressure is now fully adjustable from stock to wide open. Except yeah, I still have the cats. That's how the sound ended up being tolerable...
