We love this gasket! If you've been blowing out your exhaust flange gasket, we recommend trying this one. It does require just a hair of modification but nothing serious. It's always a good idea to ensure you've got good flat surfaces between pipe flange and exhaust manifold. If you're getting ready to install a new exhaust system the time has come to pick up a couple of these guys! For the truly unruley Interceptor, sometimes placing 2 gaskets on the misbehaving side takes care of it!
