Re: Exhaust Question

Hi Raul, the way to dampen the stress between the joints is as we do with the STEBRO/Vanagon Stainless Steel Exhaust System. We use a fibre doughnut gasket, between the joints, with a steel insert which is about 1/2" longer than the thickness of the doughnut gasket allowing 1/4" to protrude from either end. The fibre gasket reduces the vibration stress between the joints and the metal inset keeps the gasket from being dislocated and from undue compression which causes the flange bolts to loosen and the fibre gasket to then burn up form escaping hot exhaust gases. The fibre doughnut gaskets are readily available and any FLAPS and any muffler shop can cut and install the inserts for you. The bolts should not have any type of spring locking washer but instead should have a locking nut. We have been unsuccessful in finding all metal SS locking nuts and have been using SS nylock ones with success. Seems the nylon melts and keeps the nut from coming loose. They of course cannot be reused one taken apart, so you should get yourself extras just in case.

Cheers
