I got an offer from a guy on here, he wants to trade my stock exhaust +300$ for his Milltek exhaust that he had modified to fit his sedan. I've searched on here for reviews and everyone says it sounds pretty good and it supposedly adds 10-12hp. I just don't want to trade and it be awful and end up being stuck with it. Anyway, Is this a good deal and is this milltek worth it? Thanks!

P.S. I looked on youtube and couldn't find any good sounds clips, would anyone know where else to look? T.I.A!
