does the angle of the tube make a difference? from what i read it should right? the goal is to cross the targeted sound waves at 90* to cancel them correct? Looks like your is less than 90 but still works. I put one in the exhaust i just made, the quarter wave tube is at like maybe 45-60*. and i put it way up front to hide it. i cant really tell if its workin to great or if the muffler just sucks and cant be dialed down....any ideas? i got a summit jones 18" glasspack w ebay DTM cheapo muffler. Its quite loud even after puttin in the glaspack.
