For sale: Denali muffler, half-gutted by myself. Its sound is very beautiful, clear, not annoying, and excellent for airflow, it doesn't suffocate or backpressure. Also for sale: Sierra 2500HD muffler, half-gutted as well, and its sound is slightly louder than the Denali's. And a Sierra 1500 leaf spring, clean, just needs cleaning and a better paint job. Whoever is serious, I won't shortchange them, and shipping is available. 0552746385
