Ok I am about to buy a corsa cat-back exhaust off an 05 GMC CC Sierra 5.3 for my 01 GMC Sierra ECSB. My first question is will it fit?? My second question if it fits do can I just take it to a muffler shop to get it installed. I am pretty sure it is the full cat-back system and I know it is stainless. Please fill me in on the details

 

CCs are longer than ECs so I don't believe it will fit. There are different part numbers for each version. If it did fit, then the install wouldn't be bad at all. That can usually be done in an hour or less.
