And then I went to work with the hardpipe kit. Everything looked very promising. A new muffler delete with a bigger diameter
But, when I got to connecting it to the intercooler, the hardpipe kit was....smaller in diameter. In other words, everything was sent back hahah 
I was unaware that differences exist. If I remember correctly, the Cupra uses 60mm piping on the intercooler side and this was smaller...
Comparison shots
The muffler delete looks way bigger
41mm original
52mm aftermarket
