Start at 26 degrees F and a short warm up. Little smoke (I use Cetane boost which helps) just some steam. Stock muffler; I've thought about the muffler delete, but I like the rumble. Then after a day of driving a quick warm start. Nothing sounds like this beast (now that it is "free breathing"); and the torque is truly addicting.
