Why Upgrade to an MRT Exhaust?

  • Deeper, aggressive tone – MRT systems unlock your Wrangler’s true voice, with options ranging from trail-balanced to race-inspired sound.
  • Performance gains – By reducing backpressure and improving flow, MRT exhausts help your Jeep breathe better.
  • Durability – T304 stainless steel construction stands up to off-road abuse, mud, salt, and heat cycling.
  • Easy install – Most systems bolt on using stock hangers. No tuning required.

Which MRT Exhaust Fits Your Jeep?

  • For Rubicon 392 drivers: The Street Race H Pipe is perfect for those who want to amplify their Jeep’s already powerful V8 growl.
  • For Jeep JL owners: Choose the Trail Rated Axle Back for a balanced tone or the King of the Hill Axle Back if you want maximum volume and character.
  • For customization: Pick your finish—polished chrome for a classic shine or black matte tips for a stealth look.

FAQs About MRT Jeep Exhaust Systems

Q1: Will an MRT exhaust fit my Jeep Wrangler JL without modifications?

Yes, MRT systems are designed as direct bolt-on upgrades using factory hangers. No cutting or welding is typically required.

Q2: How loud are the MRT King of the Hill vs Trail Rated systems?

The King of the Hill axle-back offers a noticeably louder, more aggressive sound, while the Trail Rated system balances performance tone with comfortable daily driving.

Q3: Is tuning required after installing an MRT exhaust on my Jeep Wrangler JL?

No, tuning is not required, but it can improve performance for these “off-road only” exhaust upgrades. MRT systems decrease backpressure and improve exhaust flow, so they work seamlessly with your factory ECU.

Q4: What materials are MRT Jeep exhausts made from?

All systems use T304 stainless steel, which resists rust and corrosion better than cheaper alternatives like aluminized steel.

Q5: Can I install an MRT Wrangler exhaust at home?

Yes—many Jeep owners install MRT systems in their driveway or garage with basic hand tools. Average install time is 1–3 hours.
