Exhaust Cutout?

Curious, has anybody considered or pulled the trigger on an exhaust cutout? I'm not sure how much room we have to work with but considering our motor, a dump after the downpipe may yield some surprising gains.

I don't think we have any issues with boost creep, like some other applications but can anyone think of why this may cause mechanical harm?

This is something I was toying around with - loud with the extra power, when you want it. Quiet and a bit more subdued, when you don't.

The Rogue has the cutout in front of the rear muffler. You can add an eclectic cutout to it for extra $$$. Even left open it was still streetable thanks to the silencer.

This sounds really cool! With the stock DP I imagine that with the cutout open, it would be very livable considering the turbo to quiet things down.

You happen to know when Rogue is planning their release?
