max250

thanks guys, i have tried the fuel change with no success. so i'm thinking maybe a resonator or full exhaust change.....$$$$$ i'll let u know if it works.

hi guys/girls....... new here and have an IS250 that smells like rotten egg at high revs.love my car but cant stand the smell. have read that it may be due to a Cat problem on 2006/2007 models? if so any suggestions for a good aftermarket exhaust (inc CAT) that doesnt sound obnoxious... any help would be appreciated. thanks
