Here are some pics of my kit installed. I painted the intercooler black to match the sleeper look, so you can't really see it but if you know it is there, it isn't that hard to tell.
I actually didn't have to modify the bumper at all to get the intercooler to fit. You will have to trim the splash guard on the drivers side to get the second charge pipe through to the intercooler but a reciprocating saw quickly took care of that.
Also, those two black panels on my bumper hide the blue couplings of the intercooler, so you cannot see at all. The only thing you will have to modify to get the intercooler to fit is to move the AC condenser line behind the PS cooler line.
Another tip is to secure the splashguard with the two bolts that hold the bottom of the intercooler on. It says in the instructions to mount the intercooler with all the bolts but then when you put the splash guard back on, it hangs really low, so take the bolts off and secure the splashguard with them.
