The CPU has been throwing P0421 errors left and right since my OEM cats were no longer actually treating the exhaust gases. The bends, hangers, and pipes are the exact same as OEM, but as you can see from the pics, the new cats are much bigger than OEM. The larger cats did not create any clearance issues during the swap, but man are the upper bolts a pain to get to. Three words for you: "ratcheting box wrench!" While I was in there, I went with a new set of sensors and suggest you do the same. Make sure to have a code reader on hand to clear the check engine light that will inevitably come on when you turn it over the first time. ### ⭐⭐⭐ Poor Quality - Will not last on Jeep 4.0 - UPDATE *by J***R on Reviewed in the United States on October 19, 2020* Update on status. Seller was great to work with. They sent a warranty replacement and RMA to return the unit. Here's the deal though. The Eastern Catalytic assembly is still made the same way, so I'm not sure how long it will last. I added a clamp to support the weak weld on at the hanger rod, and was very careful to make sure the flanges are equally torqued. I also added all new OEM hardware at the exhaust manifold, which was an extra $40. The entire assembly is still just supported by the swedged pipes, which is still a weak point because the pipe thins after that process. Not sure how others are manufactured, but assuming this is where the significant difference in cost is attributed. Changing to 3 stars (5 for seller / 1 for product). Hope this helps..I installed this on my 2005 Jeep Wrangler Unlimited. Thought it was a great deal at first, but kept having problems with the flanges loosening up and the back cat would always touch the transfer case. Finally when the Jeep wouldnt pass emission inspection, I removed the assembly and found that the weld had broken, which was causing excess movement. The back flange mount had bent a little under the heat that the swedge had cracked. This is a poor design. The entire assembly is hanging on the small swedges and there is not enough material to hold the system against the exhaust manifold. SAVE YOUR TIME and MONEY and just purchase a quality replacement. You get what you pay for and expect to replace this again within a couple of years. I reached out to the seller for comment and warranty information, but no response yet. My next step before replacing is to see if a local exhaust shop can repair and improve the flanges because the cats seem to be in good shape. ### ⭐⭐⭐⭐⭐ Perfect Converter/Awesome Seller *by H***D on Reviewed in the United States on November 12, 2018* Easy install on my 2006 Jeep LJ Unlimited. It came in two pieces which made installation super easy. Just remember it is easier to drop the skid plate to get at the muffler bolts. Make sure you get a 2.5” lap joint exhaust band clamp. The unit is in two pieces and could use the added support of the lap joint clamp over the cheap u-clamp. The u-joint it comes with doesn’t hold the two pieces together.This is the lap joint clamp I used:EVIL ENERGY 2.5" Lap Joint Exhaust Band Clamp Exhaust Repair Preformed 304 Stainless Steel https://www.amazon.com/dp/B078TVV4FT/ref=cm_sw_r_cp_api_i_8R9cDb5Y9RS5ZUpdate:This Seller is amazing. Unfortunately, I had an issue with my unit where the welds didn’t hold up. The catalytic converter had lasted me only 5 months use before I noticed my engine light back on. I contacted the seller and in no time they accepted my refund. I quickly ordered a new one which was updated and even better than the first unit! This one will hold up nicely. I noticed a more compact routing which more closely hugs the oil pan and lack of dimples than the first converter. 5 stars for the product and customer service! I’m so grateful to have my Jeep up and running. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/56154678-20379-49-state-catalytic-converter](https://www.desertcart.co.uk/products/56154678-20379-49-state-catalytic-converter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
