Glad to her that you liked the engine. The engine really has done well for itself. Also you may want to try to use the new 3031 pipeset as well. We tested with it and were pleased wth the results. Alot of people are running the 2013 and they have said they also work well. We used the 2052 on the old series engines as well as the Mega line so we would get more top speed. Let us know how that works. I would use a medium length header with that pipe to start.
