This is the great performing and great sounding exhaust upgrade you have been looking for to give your WJ the horsepower, torque and fuel economy boost you need. This high quality system is complete with:
  • 100% welded baffled performance muffler
  • -OR- Premium Duty Hybrid
  • -OR- Flowmaster Super 40
  • Aggressive sound outside with minimal noise transmitted inside the vehicle!
  • Fully aluminized steel muffler and tail pipe
  • 3" Mandrel bent tail pipe.
  • Heavy duty zinc plated clamps and hangers


Add a Magnaflow High Flow Catalytic Converter for even more gain. These cats even come with an O2 sensor bung installed. Adding this high flow cat does increase the flow of your exhaust, also making it grumble with an even deeper tone. NOTE: This Magnaflow Catalytic Converter is NOT 50 State Compliant.

We did our own independent test with our cat back system versus stock exhaust to see what performance gains could be made. The ONLY modification we did to our 4.7 HO WJ was remove everything from behind the catalytic converter and replace it with our 3" FLO-PRO Hybrid and 3" tailpipe. We ran multiple quarter miles with each system and averaged them to see if there was any difference. With stock exhaust we averaged 17.62 seconds and with our 3" cat back we averaged 17.14; an improvement of .48 second!!! With this impressive result, we conclude that you can you can achieve .35-.65 .35 second shaved from your 1/4 mile time just from the higher flow exhaust system! Make the next step in your performance upgrades a cat back exhaust.

I installed this 3" tailpipe and flowmaster exhaust on my 2002 Grand Cherokee with a 4.7ho engine and LOVE the sound it makes. I used a 44 series muffler and added 3" pipe up to the end of the cat with an adapter. Bends in the tailpipe are perfect. Nothing hitting body over bumps. Highly recommend if refuse to give up your WJ !
