croracer, For a truggy either pipe will work great.I like the punch that the 2013 delivers for a truggy. The 2035 still has great power but a little less punch on the bottom. The mileage WIll be pretty close. I tested the 2035 a couple weeks ago and compared runtimes and they were pretty close, and I actually seemed to get about 20 second s more from the 2013.
