well got the mufflers on, PEX TRIPLE FLOW, and while the sound quality is better, still got that bloody drone !!! not as bad but still annoying me a bit, going to slip in a long fluted dog monday to hopefully fix it. also I have got some flexible hose and gone from an SRI to a CAI down in the guard. was looking at the mesh pattern next to the foglights, was thinking to knock centers out for more air. I will resist this cause I will prolly wreck it !
