The Silverline is very similar to the MBRP in fit and finish, but don't have the flange where the cat delete pipe is on the MBRP. It comes with the cat delete and is a real nice system if you have an LB7 without the cat. Also, the Silverline system comes w/ a dual wall tip that looks real sweet! The Silverline muffler don't have any welds on it either. It shouldn't rust at the welds like the others do. My buddy has one on his LB7...Sounds great!
I started stock, then went w/ the Magnaflow cat back...loved it....added the MBRP front pipe and loved it more, then deleted the muffler w/ the MBRP muffler delete pipe....good sound, but anoying at times...back to a silverline muffler and MBRP cat delete. All 409 by the way! Maybe duals next!
