you can just drop the anti roll bar mounts,that will give you a bit more room.

you have to get the car as high as you can too as you have to twist and turn the downpipe under the car to get it to fit in there.

have you put a 2wd ex manifold onto your car as i put a 1-2 inch extention in my downpipe to give me a bit more clearance,hope you will be ok.
