Revo,

I called Adam Drake and asked him. He said the 2053 is great for the engine. He said make a ton of power and that he actually stopped running the .28 because it would wheelie through bumps to much. But he could not see why some say it's the worst pipe. If you need more power than what that gives ya you may need another hobby! lol....

But I asked the best alternate pipes as well:

Jp-1 for more bottom(you won;t need that)

Jp-3 works well too.
