personally I don't think it will sit right either way without modding the exhaust somewhere.....because the header puts the turbo a little lower, so I would think that would throw off the geometry somewhere........but then I didn't test fit it in the car, and I already had their 02 pipe, but with a custom down pipe and exhaust.....so I don't have anything to reference it to.. There are members on here that have the ssac mani, so maybe they'll chime in
