Red and loud! Flowtech Red Hot mufflers are the best value on the market today. Red Hot glass packs deliver a rich and powerful sound with minimal back pressure to increase the performance of any vehicle. Each glass pack is constructed of a large 3.5” dia 16 gauge case for added durability. Internally, Red Hots use a power louver straight through core design to reduce exhaust turbulence and improve exhaust flow. FlowTech wraps the power core with a high heat Cerama-glass packing for improved sound control and internal durability against burnout. Red Hot glass packs measure 24” end to end with the actual glass pack measuring 18” in length. Installation is a snap with the slip fit design.
