this is possible also, we will have to wait for dyno results..

What is it made of anyway. At those prices it doesn't sound like 321ss.

why don't you make a scoop inducted "muffler" to alleviate the pressure in a 3 or 4" system?

ROFL! great point!

This is true - basically on a turbo car, you want to maximize the difference in pressure between the exhaust manifold (ie before the turbo) and the exhaust pipe after the turbo. The higher that pressure difference gets, the faster the hot side turbine will spin.

You can increase the pressure difference in 2 ways - make the pressure before the turbo higher (but this can cause other issues if exhaust gases aren't expelled from the cylinder) or make the pressure after the turbo lower (see larger exhaust, no cat, muffler, etc). It looks like this system is tackling the problem from the second approach in an extreme way - I'm curious to see how it turns out (videos, dynos, etc)
