Also, I have an oiled AFE filter, sould I get rid of that and get something else. I am reading more and more that oiled filters are not the way to go. Any thoughts?

First thing to do is get rid of that Bully Dog. That might be the worst thing you can do for a Dmax. A friend had one on his truck because he had it from his cummins. Truck did not run good at all. He went to a different tuner with much better results.

BigBlue the exhaust was $400 shipped which is a killer deal and I got it from Evolved Motorsports. Not really sure if they are around anymore. It is a turbo back which gets rid of the cat which is cool for me with no inspection here in Michigan. I do way to much freeway driving to deal with the drone of a straight pipe.

C9071, Does it have a nice rumble or does it sound closer to the stock exhaust?

I really like the tone. I think it has a pretty good rumble.

I do OK towing, not as good as I would like but then I have larger tires which do not help and on a 7% grade get 45 mph towing my 13000lb+ Damon. I have since added the Banks Economind/IQ and have yet to try the Horseshoe Bend Hill again.
