Solid Muffler. Good Sound!

Solid construction and good fit because.....its universal! Most of my exhaust is custom since the original rotted out so it sits only a foot off the cat pipe and turned down....if a good rumble is what your after this muffler will suffice but your scenario may differ.

40 Series Delta Flow - a great compromise
