Description
Keeps Check Engine Light at Bay. A damaged or malfunctioning catalytic convertor could trigger your check engine light and fail your Wrangler at inspection. Luckily, this Magnaflow Universal Catalytic Converter offers a universal design with slip-fit ends that will install easily to your exhaust system, though some cutting and welding may be required.
High-Flow Design. Magnaflow designed this catalytic converter with a half-inch lap joint at the neck to free up trapped airflow, unlike your restrictive stock model. In addition, this converter comes with a monolithic honeycomb catalyst and wider-sized inlets to improve airflow through your catalytic converter and free up more power.
Heat-Resistant. This converter features a ribbed steel heat shield that protects the structural integrity of the converter from extreme heat. In addition, this ribbed body minimizes gas expansion under intense heat to prevent damage to the ceramic catalyst and keep your converter intact.
Heavy-Gauge Stainless Steel. This catalytic converter is manufactured with a heavy gauge stainless steel to withstand extreme heat, chemical exposure, and abrasive conditions underneath your chassis.
Limited Lifetime Warranty. Magnaflow backs this product with a limited lifetime replacement warranty against manufacturing defects.
Application. This Catalytic Converter is compatible with all 1997-1999 2.5L or 4.0L Jeep Wrangler TJ and 2004-2006 4.0L Jeep Wrangler TJ models.

Excelllent fit
This cat fit like it should with no extra adjustments. I replaced my factory original broken cat so this put the system back to normal operation and turned the check engine light off!

Magnaflow on my TJ
added the aggressive tone I wanted without making the jeep uncomfortable while driving. i installed this with the full magnaflow cat back and banks headers. I know my jeep is not meant to go fast, but it will bark the tires in 1st and 2nd gear. makes my heart happy!

OEM replacement
Took longer to get the old one off due to seized flange bolts. Major power and performance. Engine has 213000 mile and now it runs like new.

2006 Rubicon - ShortGuy
Magnaflow Comp Series Cat Back (Cat To Bumper) Exhaust
Overall I really like this exhaust system! The exhaust note is throaty but not loud or obnoxious. It has nice durable stainless construction with a nice polished tip. I installed this on a 2006 Jeep TJ with a 4" lift and Fox 2.0 reservoir shocks. I had to cut a couple of sections apart and stainless tig weld it back together for clearance at the track bar, but it was well worth my trouble. I am ordering another today for my son's Jeep.

2001 Wrangler - Dark01TJ
Does not quite line up with stock pipes.
First off this exhaust sounds great and couldn’t be happier with that. However the flange did not line up well with the cat piping. Rotated several times to find the best seating position. I feel it is not seated well and still have blow-by.

Fantastic muffler
I much prefer the design ending before the axle, it leaves less dangling and hopping around. Less to get dented and beat up. The volume on it is great, it's throaty and mean. Not so loud it drives you nuts but loud enough to know it's there working. Hi es that seat of the pants feeling and screams down the highway.

Amazing sound
If you’re looking for an exhaust ?that has a meaty sound to it this is that exhaust. This exhaust makes the pops and bangs on downshifts. Would 100% recommend

Exact Sound I was looking for
Low deep sound, but not loud enough to wake the neighbors or become annoying at high speeds.
