Utilizing factory cut points and mounting mechanics, the Dinan exhaust system is a straightforward install with precision fitment just like you would expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipe, the upgraded system is a marked improvement from its predecessor - both in terms of material/construction as well as in overall looks. For weight savings and simplicity, the stock single to dual pipe setup has been abandoned in favor of an enlarged, free flowing single pipe system. This pathway feeds into a muffler that limits frequencies associated with drone, as well as assists in altering the overall tone of the setup to deliver the signature low Dinan rumble. The no-nonsense design allows shocking versatility in sound levels when paired with features, like valves, often associated with more fanciful alternatives. The unabashedly spartan, yet effective, pipe layout forces gasses to escape from the rear out of massive dual, straight cut, 114.3 mm (4.5-inch) exhaust tips emblazoned with the laser engraved Dinan logo. The tip branding further cementing any lingering doubt that the system visible is something above and beyond stock-- if it was not already apparent by the blissful music permeating from them.
