Strangely I've been getting varying opinions as to whether or not HFC's with a Vertible are liveable.

Cali-convertible says he doesn't notice any smell at all with his Fabspeed set up.

Thanks.
You can smell exhaust with HFC's I have Fabspeed setup and although it's not nearly as bad as no cats, it definitely smells more than OEM. You can tell there is a race cat on there.
