Ok, lets get back on Topic a bit... if youve a 1.4, there would possibly be no cut out in the bumper as the exhaust tails downwards, your new exhaust sits straight, therefore would need a section cut from the existing bumper, or for you to purchase a whole new bumper , which is possibly a tad overkill.
 
yep was wanting the cupra bumpers any way but im sure the rear is just the same but colour coded, more than likely just gonna cut it then get it painted
