Hey folks.I am replacing the single exhaust on my Ventura with a stock dual and am confused.The assembly manual says to use a sealer between the exhaust flange and pipe?No donut gasket?The exhaust manifold has a bevel to it and I don't know if that is just a hardened donut gasket or metal.I don't want to start hammering on it to find out.Do these use a donut or just some kind of sealer with metal to metal contact?Any help would be appreciated!Thanks

Thanks.I have used fire place cement that comes in a caulking tube.{used to adhere the blocks on the bottom of the fireplace}It was used on a Chevy 396 cast iron exhaust manifold that was in bad shape.Never leaked.I guess I will use that.
