I just picked up a set of 07 Gt mufflers for $30 off craigslist. I was wondering what everyone was doing to install these properly? Just bringing them to the muffler shop and getting them welded to the stock piping? Or since the Gt have larger diameter piping do I have to get a whole new cat-back welded up? Also pics would be greatly appreciated, and if im not asking for too much sound clips. Thanks.
