I have a 1999 FXR3 with a 113 S&S. The pipe I'm running is a Thunderheader.. I have the pipe rubber mounted in the rear. I've snapped the exhaust bolts twice. I remember when I first got the pipe there was a mount that came off the engine right under where the cam is. That mount broke a while ago, and I was told it didn't need to be replaced. I'm thinking it did. Is there a better way to mount this pipe to the engine so this doesn't keep happening? Thanks for any and all help.

Same happened to me from a loose p-clamp. Make sure you look over the pipe real good as mine had fine zipper cracks on the back. Had a welder weld the cracks and put it back on. Still working good even though an ugly weld is there. Nice guy only charged me $15. Bike is 96WG.

If I recall correctly the FXR's had a P-clamp around the header down by the cam cover. This must be installed to support the pipe. Since the pipe is mounted to the rear of the frame there is a lot of stress that occurs at the heads when the P clamp is not installed. Also be sure your front motor mount is in good shape. A worn out mount will allow excess movement of the engine in the frame.

Assuming his pipe still uses the stock support brackets:

thank you all for the replies! I will definitely inspect the pipe when I pull it. I'll also check the motor mounts and the rear mount. Where can I get that mount that mounts under the cam inspection plate? It's not a stock motor, but a S&S 113. I do remember there being a mount there in the when I first bought the pipe, but that broke and I was told I didn't need it..I know bad advice, obviously..
Thanks again for all the help

The bracket is 65670-82B. Obsolete from Harley. The clamp is 65302-82A. Still shows available.
The bracket lives in the aftermarket though. In the "ask and you shall receive" category click the link below:

^^ Do an ebay search by the clamp part number while you're there. Will likely find several if not many used or aftermarket options. Common part on many bikes for a long time.
