Flowmasters new American Thunder axle-back system for the 2018-2019 Jeep Wrangler JL is perfect for the person looking for maximum performance and ground clearance from their exhaust system. This 2.50 inch system features a 409S stainless steel mandrel bent tailpipe with a 3.00 inch polished stainless steel tip and fits both 2 and 4 door models with the 3.6L V6 engine. This system replaces the factory transverse muffler providing a moderate to aggressive sound level. This allows for better ground clearance when driving off-road. Because the tailpipe is tucked up so high, an aftermarket metal bumper is recommended. Designed for an easy fit, this system includes all necessary parts and hardware for installation.Warranty Information:Limited LifetimeCalifornia Proposition 65 Chemical Name 1: LeadCalifornia Proposition 65 Chemical Name 2: ChromiumCatalytic Converter Included: NoExhaust Series: American ThunderExhaust Type: Axle-BackExit Position: Side Out RearHeat Shield Included: NoInlet Inside Diameter: 2.500 in.Material: 409 Stainless SteelMount Type: Uses Factory HangersMuffler Part Number: Kit OnlyMuffler Series: NoneSingle or Dual: SingleSound Level: ModerateSystem Type: Axle BackTail Pipe Diameter: 2.500 in.Tip Cut: AngleTip Diameter: 3.000 in.Tip Edge Style: CutTip Finish: PolishedTip Length: 3.250 in.Tip Logo: NoneTip Material: 304 Stainless SteelTip Quantity: 1Tip Shape: RoundTip Type: Single WallTubing Diameter: 2.500 in.Tubing Material: 409S Stainless SteelWARNING CA Proposition 65: YesWARNING CA Proposition 65 Message: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
