I put a set of DL10s on my 2006 C10 about 3 or 4 years ago. at the time they were about the only aftermarket support i could find. i was looking to take as much weight off the C10 as i could in places that made sense and a lighter exhaust system makes sense to me. the mufflers were about 1/2 the weight of the stock ones. all the hardware fit correctly. there was no missing hardware. all the parts were wrapped/bagged/cushioned so no shipping damage or scratches. the non muffler hardware/pipes were all made of stainless steel. of course the mufflers themselves have that carbon fiber outer shell. i liked the looks of the DL10 outlets. the finished install did not interfere with the sidecases in any way. even with the db killers left in place the bike is louder than stock. wrt the sound level there are + and - with being louder than stock. you'll need to decide that for yourself. if you're wanting to reduce the weight of the stock C10, these will help, and you should have no issues with the kit based upon how it went for me if you are installing it yourself.
