M10 x 40 long (5-off) should do it. You will notice the performance improvement. I thought that this mod would just make the car sound as if it had more power, but it really does have more power.
The extra boominess in the cab is not to everyones liking, so hang onto that original box for a few weeks just in case. I did, but have now dumped it.

I had cat removed and centre silencer leaving just the small back box, it sounded amazing, then MOT regulations in N Ireland changed and had to put CAT back on 
which quietens it a fair bit.
