Here's what I have and know, A DLE55 with a 'JTEC WRAP AROUND PITTS' Muffler on a TF Giant P-40; the Muffler features Long Exhaust Tubes, my thought was, the Vibration and shaking of the Engine will shake the Muffler to a point the Muffler will crack and fall apart, despite how solid the engine feels mounted on the Standoffs, the Engine still Vibrates, Flexes and Shakes, no more than normal and what would be expected, Firewall Flexing, etc,.

A few Guys have stated their Wrap Around Pitts Mufflers have failed this way and they were using Jtec, in assuming that my Muffler does not come loose which some have stated has happened and probably contributed to the Muffler Cracks and Failure, I will be using Wire Lockable Bolts. Is using a Support Strap, mounted to the Muffler End Plate and secured between the Engine Mounting Bolts and Standoff; Overkill, Not Recommended, etc?

JTEC does not recommend Support Straps and states that using one Voids the Warranty, besides voiding the Warranty what will it Hurt?

Thanks.
