I have no intentions what so ever to use this filter, even if it was 3'' like the lower pipe. Before ordering it i already had plans to replace it with a aem or k&n 3''. The lower pipe is 3'' the upper pipe is 2.75ish so i guess the lower IS
the filter it came with is 2.5'' it doesnt even fit the upper pipe :( lol
