2006 2010 Volkswagen GTI 2 0T FSI TSI Ccta MKV 3" Turbo Exhaust Downpipe | eBay

This is super cheap! But is it the right one? I would also consider one for my pre-fl VRS. But I can't figure out which one suits.

Does someone know if they give the car a better note, and what power differences can be found? Also, what is swapped/cut out when installing this?
Cheers
