I just installed the IED wires and a Ness Big Sucker to go with my V&H Oval Slip ons on my 08 Street Glide . There does seem to be a significant improvement in the way the bike sounds and pulls . The Ness system is way better than the HD one for sure and the wires took about 30 minutes to completely install and secure nicely . If the bike doesn't show any adverse signs when the hot days get here I will be totally happy with this set up .
