Are you guys stupid or something, you don't even know who you talkin to.....Your talkin to Mickey Dunlap of Four-Stroke Tech. He's built some respectable engines. Two I know of would be Chad Duvalls and the first Z500

Well I can say after testing the LTE system this weekend Iam very happy that the system work great! The pipe I tested was on a full race 470yfz which had a full race White Brother meg system. Both ran the same everywhere BUT the LTE was running the quiet cores. We are currently sponsored by WB so we will get one of there new quiet core pipes from the and see if it will work.
