Reduce Vibration To Muffler

[Listerational]

Hello,
I have a Powerline 10/1 with a 10' X 2" pipe and muffler exhaust assembly system. There is no place to add a piece of flexible 2" line at the beginning of the assembly without cutting a new hole in my garage roof for the new pipe location. I was thinking about replacing the system with a piece of flexible 2" hose about 10' long. I do not like the idea but it beats cracking my cylinder. Are there any other methods to reduce vibration to a muffler / pipe assembly other than the standard flex hoses offered on the market?
Thanks,
Jim

Why would you have to do that if you have 10 feet of pipe? If it is just a matter of supporting the weight then makes something to support the weight. I used a 18" piece of 2" flexible pipe  shortly after the engine flange bad then just set up a support fur the weight for the rest of the exhaust pipe. Post some pics

So it comes out of the head horizontal and then turns vertical  after how far?  You could put the flex section in right after the upward turn which would de-couple all the vertical mass...

+1 Ronmar's suggestion. If the 10 feet is all vertical, just put the stainless flex section right after the turn up.  Use muffler hangers with rubber bits (from your muffler shop) to suspend the vertical section just below the roof.  You don't want that weight on the flex section or the exhaust manifold/head.

Hello,
         I will also be piping the exhaust of my SR out of my garage.  Even though I am not ready to install in the garage I wanted to reduce stress on the exhaust manifold so I installed a stainless steel flex coupling that is used in modifying car exhaust systems. I bought the coupling from JEGS (www.jegs.com):

Intelligent solution, thanks.

Interesting flex coupling PaperPatched. Is it sealed from gases leaking out of it?

We also use the stainless steel flex couplings in our exhaust runs... somewhat longer through the bellows and also reinforced on the outside with metal braid. These are sealed and last a very long time if not stressed too much.

Advanced auto parts sells a reinforced section of flex tubing that can be fitted to an exhaust. These are quite capable of handling movement, as they are designed for Front Wheel Drive cars, where the engine rotates forward/aft on each shift.

  Have the engine been 100% balanced in either the vertical or horizontal plane? That would almost eliminate motion along one axis.
