Thunder header

just got a thunder header for my fxr its a 90 got it off ebay came with a big ugly mounting bracket but ive looked an looked an can find no info on how this things mounts using this bracket could sure use some advice thanks

I've never installed a T-header, but when you remove the stock exhaust system mounting brackets, the T-header bracket mounts should line up with the mounting points on the bike,and the other mounts to the muffler if you have the right bracket for a FXR. Should be pretty simple, just line up the holes.
Like Chuck just asked " is the exhaust system for your model??

suppose to have come off a fxr with forward controls which is what i needed i had a set of bub bigdogs on an all it has is a tranny mount dont really no what the stock mounts look like

I'm not sure if the FXR used the same bracket as the Dyna did..any FXR I saw with a T Header had some small bracket support the pipe from the rear. Dynas had a big honkin bracket that tied the nose cone and the tranny together and then there was a long tubular section that ran rearwards and that was where you attached the rear mount of the pipe so the pipe moved with the motor. You may have a Dyna pipe

I think the FXR engine is rubber mounted, isn't it? If so then the exhaust mounting bracket wouldn't be on the frame. I would think the bub mounting bracket is mounted in the same place as the stock exhaust bracket would be and the T-header bracket should mount to the bike in the same place also.
FXR's and Dyna's(FXD) are different.
If you can post a pic of your bike and exhaust, it would help you get an correct answer.

here's a couple of pics of Thunderheaders. one setup is for an EVO Dyna, thats the one with the big ugly bracket that goes from the nose cone to the tranny.supports the right side of the motor, a sort of cheap carlini torque arm and the long rod from the back of the bracket supports the rear mount of the pipe so it all moves with the motor. The FXR rear mount is a flat piece of metal that attaches the rear mount of the pipe to the frame

thanks for the help i looked at the pics sleepy posted an seen the bracket for the fxr, looks like i got part of the bracket for the dyna

FXR mounting

The exhaust mounts for my FXR and my Road King both bolted to the trap door bolts on the tranny. Just make sure you remember it's
a rubber mounted motor.
