Second suggestion: if you are unable to find a local Weber expert or are immune to pain and thus are a do-it-yerselfer, try e-mailing Byron Hight of Nor-Cal Panteras. Byron currently has Webers & 180 degree exhausts and IS such an expert (the Webers were mine and he had to do significant tuning to get them to run on his car) (byron_c_hight@amat.com).
