Summit exhaust systems, are they decent?

well got it all in, went smooth for the most part but didnt end up using the front peice for each side cause my old exhaust lined up with it and i had a 2 bolt header flange not 3 which is what the kit gives. deffanitly putting my other mufflers back on, very upset with the ones they give you. still gotta line them up in the back and trim one side of the tail pipe back. heres some pics
