Has anyone had any experience with Thunderheader slip on's. I have an '05 SEEG and just wondering how they fit and sound. Do I have to re-map the EFI? Any information would be appreciated!!

I was told by my local dyno gut, who I trust, to stay away from the Thunder Header Slip ons. If you like the sound and looks of the thunder header its best to go with the complete pipe and the false left side if you desire to have both pipes. That pipe works very well and has great sound. As far as the sound my friend has the slip ons on a 02 road king and they pop and crackle quite a bit when he decelerates. If you do decide to go with them you will definalely need a remap and a high flow AC kit


I had the Thunder header on my last bike but chose the Freedom setup for my SEEG. Check out the Freedom pipe thread there is a bunch of info there. Here's the link.
