The GM Factory Mouth Piece restricts air flow to the turbo. The LDS 3.5" Turbo Horn increases air flow resulting in faster spool-up, enhanced turbo whistle, and increased HP. Works great with Factory and drop in replacement turbo's, and the Custom Powder Coating really classes up the engine compartment.
