Yep....... Another exhaust question. [SC400]
I'm wondering if there's a cutout controlled by vacuum. If there is one, then I can think of some turbo manifold using it to function like a sequential turbo system.

nope there is currently one that is electrical and one cable there was a engineer that came though to test a prototype that would open up the cutout based on the amount of pressure from the exhaust flowing through the exhaust

300-600 bucks for a manifold is a far cry from 1k...and considering a good quality cutout is about 150-300 depending on manufacture and the labor you'd spend to weld it into place around 150... why not pay an extra 100-200 to get some sound and performance??.......if you hate hearing the truth don't ask on forums for opinons and facts

I surely do appreciate your response, it's the most informative for sure.
So I'd be good with getting a 2.5" cutout?
I never thought about the side exiting problem, but it makes complete sense.
After researching the different companies (QTP it seems, being the most popular) I chose DMH because of the customer service and mainly the 4 year warranty. I'll look into pypes for sure though. QTP has the most hype and least deliverance it seems. Shoddy construction.
I appreciate your response!

Yeah, the DMH appears to have a "Flowtech" which is basically just a pipe extension.. I think I'm going to get our fabricator to fab up a longer extension to exit out the passenger side, but not all the way out, because that would look ridiculous. I'm pretty excited though, do you have any more insight into the matter? I think it'd be a pretty cool addition to the car, not to mention it would sound sick.

Yeah, I have the same Flowtech cutout Y-pipe that comes with the DMH. You could get a tip custom-made for it. After I lost my first turndown I bought another longer tip (on summitracing.com) but it wasn't exactly what I was wanting and couldn't really tell how it would look and fit from the picture, so need to have it cut down a little to basically look like a longer version of my old turndown. It just sounds great with a turndown after watching and hearing some of my old videos I put on YouTube.

For some reason I couldn't figure out that you were the same guy who posted up those videos, it sounds awesome.
Getting a quote tomorrow, but I think I can get it welded up for free. If so, all I have to do is worry about wiring. I need to get a better look at the switch to find out where I can mount it inside the car to make it look OEM as possible. I was thinking I could wire it into the ECT switch so when I put it in "PWR" mode, it opens it. That would make selling the car hilarious. "Oh yeah, and when you put it into sport mode here... *Rumble Rumble Rumble*"

That would be kinda sweet if you could make it work with the ECT switch or you could just put it somewhere else so you don't have to splice into the factory wiring, etc. I might wire it up myself when/if I get an electric addition, so you might have to write up a simple tutorial/DIY with some pictures of your setup afterwards, where you routed the wires and how to get the switch up into the cabin.

Unfortunately, didn't have the pleasure of driving one, but the first guy in the pictures did.
The owner has FOURTEEN of them, selling for profit. I don't think he really even likes the cars, he just wants the $$.

So I figure what I'm going to do is... (And I need input on this one.)
Take out the center cat(Midpipe) and put in a test pipe.
Then I'm going to buy one 2.5" electric cutout and weld that into the test pipe.
That will:
A) When the exhaust is running "normal" it will still be a little louder than stock, due to the deletion of center cat.
B) Save me about 200 bucks on getting just 1 cutout instead of 2.
