MagnaFlow's revolutionary xMOD Series #19495 offers a completely modular exhaust system that takes modifying your vehicleâ€s exhaust to the next level of personalization. The configurable sound level provided by Supra xMOD Muffler Modules and MagnaFlow's proven straight-through 5" round 8" long 3" core mufflers now feature race bred quick release v-band clamps for quick installation and removal for when you want that race car sound instead of the deep aggressive signature MagnaFlow exhaust note. Supra xMOD xTreme Deletes are equipped with the same v-band clamps allowing for the removal of the muffler modules for that xMOD xTreme near-straight pipe sound experience. Please note while the xMOD systems are 100% emissions legal the use of the xTreme deletes is recommended for track use only. Check local sound laws for street legality. Expandable flow capacity for big power mods with Supra xMOD Opti-Flow Modules feature fast-flowing 3" mandrel bent stainless steel design correcting the flow restrictions of the ovalized factory pipe trading better ground clearance for total flow. The xMOD Opti-Flow Modules are optimized for stock power plus minor modifications. Supra xMOD xTreme Flow Modules: feature increased flow capacity with a 3.5" mandrel bent big bore designed for big power modification support. The xMOD xTreme Flow Modules increase airflow up to 36%. #19495 retains the Sport mode exhaust valve functionality and provides a modest power gain over stock. The kit features 100% durable stainless-steel construction and is backed by MagnaFlowâ€s limited lifetime warranty.
