Like most things, I have my own way of doing Power Flows

Check out the pics.

I'm a Power Flow Systems dealer because I think they make a superior product; I don't waste time on products I don't like. The PFS is not cheap. I imagine it wasn't cheap to get certified either. The fit and finish are far superior to the factory exhaust.  Call for pricing. I'll make it worth your while.

 

I do not install the PFS exactly according to the instructions. I'm not a big fan of the long support rod for the muffler (I only install the short stack). 
What I do (for the Tiger) is bent the support rod so it goes over the engine mount. I use an ADEL clamp to protect the mount. Check the pics.
