Weber DCOE Air Horns

[Joe Curry <spitlist@gte.net>]

I have an opportunity to pick up some bent air horns for my DCOE40's and was 
wondering if anybody on the list has any experience with
those.  They are about 2" long but one side is about 1/8" longer while the 
other end is about 1/8" shorter, making them face not
straight out but at an angle.

Should I get these or will they hurt performance rather than help?

Regards,
