[QUOTE="Bad Company, post: 15536501, member: 141815"] J Behind the X-pipe and before the mid-pipe you can add a set of 60mm turbo wastegates as dump valves. This would allow you to adjust the opening point by boost pressure in the intake manifold. It would be completely automatic or you could also install a boost controller to shut them off when on the street. I don't know if there is enough room under the car to do this. I like this thought over electric cutouts due to the fact a wastegate is easily rebuilt if it starts leaking, plus I like how the valve closes which will seal against exhaust gases better than an electric exhaust cutouts. I also like the Corsa mufflers as they have a 3" through pipe in the core of the muffler. They flow better than any baffled muffler design, yet are extremely quiet under standard driving conditions. The only thing is you'll have to cut off the 2.75" ball joint connector and weld a 3" pipe to match your existing piping. Yet with the internal piping in the Corsa being 3" then you'll have a complete 3" exhaust with a high flow muffler that will not drone at cruise conditions The cross sectional width of the 3" exhaust piping and the 60mm wastegates will actually be larger in diameter than your current 3.5" collector of your headers, it will be the equivalent to having a 3.75" exhaust system when the wastegates are open under boost conditions. To limit some of the noise under the car when the wastegates are open you could do custom piping from the wastegates to the front of the tires in a similar manner as to the 2012 Boss 302 cars. I don't know if there is enough room under the car to do this in the 2.25" piping that would be required after the wastegates to flow the exhaust volume of doing a short turn down under the car at the wastegates The only downside is how much the wastegates cost. It is an idea that remedies a lot of problems associated with electric cutouts, leaves you the option of adjusting when they open at what boost point in the intake manifold by changing springs. And you could add a boost controller to keep it shut for street use. [/QUOTE]
