AE/TTR 2035 and Nova 9853 (and its Ofna and Dynamite copies) seem to work pretty well. The OD pipe may well be the best but obviously you cannot get it right now. Run time is at least 8 minutes in a buggy. I think it may get better as it breaks in. Power is smooth and seemingly limitless top end. The engine has a very crisp sound too. I think you will like it in a buggy. I have not tried or seen it tried in a truggy yet.
