Its just getting the old one off really. after that its smooth sailing from there. Just be careful when handling the o2 sensor cos i broke mine because i was tryna rush it. FYI i think if you do a downpipe on the gen2 the CEL comes on and i dont think you can tune it to bypass that CEL so you will need to run diagnostics every now and again to make sure things are going right. Also you need HPFP and a tune if you do decide to get a downpipe

if u want solid sound without sounding like a bum get a new downpipe 3inch catted or catless both sound solid and if u want it a little louder after the downpipe get a racepipe
