I really don't mind the smell at all, but don't want the extra attention from police/epa. We apparently have these ba$tard vans that take emissions readings on on-ramps in VA, then mail you a ticket...some for thousands of dollars. I had test pipes on my car before it was TT and it didn't bother me one bit. Now that the car is TT, it is running a little more rich (need to get a custom tune) and the smell is much more noticeable.
