Underdrive pulleys for split port 3.8

Where can I get an under drive kit for a 99-04 3.8 mustang? I cant find them online. I only find 94-98 under drive pulleys.

Also are they worth it? Would i notice some hp or torque?

The maxim gain is 10 hp. But if you do not regularly rev your engine to 7000 rpms you will only see a hp or 2. Basically you can rev your engine up higher and faster with a udp. But I love mine and it's better to know the truth before you buy.http://www.rpmoutlet.com/musv6asp.htm
