blwblw: Now that my Evo has been rebuilt, I'm like you, really happy with it. It performs as well as any other sport .46 out there. And, switching to the Tower muffler really opened up the engine. I think you will like this combo too.

Thanks for the tip about the hi-temp thread locking Permatex. I didn't use this, rather I tried regular thread-lock. If this problem reoccurs I will try it out.
