Do the dpf delete and if you want the best sound i would do a 5", i have a LMM and run the quadzilla and the 5" MBRP with a muffler delete. The only way to get exhaust sound is to delete the dpf. If have question lets me know or give me a call.

I agree with Tyler. Get a system with a DPF delete. I think you'll also need a programmer that programs the truck to know the DPF isnt there as well. A intake will help make the turbo whistle louder as well. Check this thread to I think the new LMM's have a resignator. Pluging it off will make the turbo a little louder.

Louder whistle sounds good.

I hope not, there sure are a lot of use that are running straight piped. No problems here.

Deleting your DPF will help considerably!! It will not mess anything up as long as you delete the codes caused by the removal. To do that, you will need a tuner such as the PPE Xcelerator Standard. In addition, a set of boost and pyro gauges are highly recommended.

As for exhaust systems, it depends on what you are looking for. MBRP turboback systems are top sellers but do not include the downpipe. The factory one is "ok" but when you start adding power, its the weak link. DiamondEye makes their turboback systems WITH the downpipe and are actually cheaper than the MBRP system is, should you order their downpipe as well. Close to $100 cheaper!

PM me and we can discuss pricing, if you are interested. Also keep in mind your mpg improvement by doing these mods will be WELL worth it.

Running a full system will not mess anything up, as long as you get the proper electronics to go with it. You will need a programmer to take care of codes and to disable regen. We have several different packages for this depending on your budget and exhaust wants/needs. Feel free to contact me with any questions you may have.
