I replaced the just original muffler with the 50 series It gave it a deeper throaty sound I was looking for. In fact it could have been a little louder. You will need to bring about 16" of 3.5 inch exhaust pipe to your local muffler shop for the install. For some reason they don't carry pipe that big
After receiving my exhaust system, reading the limited instruction form and checking everything that was supplied. There was nothing to attach the new system to the DPF filter. The exhaust that is to be discarded, has the pressed in studs, for attachment. No bolts, studs with nuts, nothing on the instruction sheet or let in the box. Additional purcase of three proper bolts is required.

More than happy with this system. Replaced factory dual exhaust. With 2 guys and torches, it took less than an hour to take old system off and put new system on. Sounds excellent. Thought about replacing just the muffler with a Mufflex muffler...glad I spent the extra money. Sounds much better than my buddy's Mufflex.
