Awesome replacement

Great price for high flow cats! I love around with some leaking headers for a long time - a little too long. Damaged the stick cats and the dealer wanted $3000.00 for them. I remember a buddy had to replace his a few months ago on his Toyota and he said they $3000.00. I laughed and said no way, but it's true. Anyway Autoanything saved me alot of money on these and shipped them out fast, minimizing my down time. Truck is back together and running great. Thanks alot.

Second one

This is my second one. The first one started rattling inside and then died after about 2 years. Hope this one works better.

Great Product at a Great Price!

My factory OEM catalytic converters were dead but were very expensive to replace. I added these to my Flowmaster cat-back exhaust system. My order arrived when expected and the installation was painless. I don't notice too much of a performance difference but I am still pleased with my overall purchase. I encourage you to use Auto Anything's Live Chat to negotiate the best deal. Thanks Auto Anything!!!

cats

I have not installed them yet as had problem removing one. They appear to be exact fit. The cats themselves are smaller so lighter. The right side cat came with two bungs for o2 sensors when only one will be used. A plug/cap should have been included. Try finding one

Flowmaster 98 Jeep XJ

The cat itself is well constructed, with sleeve fit into existing exhaust. Small notch cut-out was needed to fit across preexisting metal tab on my 98 Jeep XJ. CONS: Clamps included were of questionable quality (one broke during install with hand tool); I separately purchased heavy duty clamps, which provided good seal.

Happy

The Flowmaster Catalytic Converters were a proper fit, there is some resonance that I am working to get rid of, but overall I am happy with my purchase, it arrived quickly and was what was ordered.

relatively easy to install, good quality, 1/2 the cost of OEM.

The internal monolith in one of my factory cats broke loose on my 2003 Avalanche which is a common problem in GM trucks of that age. It was rattling around and caused a catalyst efficiency check engine code. GM Dealer wanted $1500 to source and install their $800 part. The chat window opened and a parts specialist confirmed fit for my application and even knocked a little more off the price. They beat Jegs, Summit, Rock Auto pricing substantially.

Just right

I had a cat that was giving a check engine for low performance, replaced with flowmaster caTs no more check engine. They do what they say, next I'll be putting on flowmaster mufflers

Questionable craftsmanship

driver side cat was not manufactured well. It properly fit into place but the hole for the O2 sensor was machined off center. One of the two bolts for the o2 sensor was also bent. Had to have it professionally reamed and a new bolt put in. Other than that 70 dollar fix, the cats themselves seem to be pretty decent.

Very satisfied!!!

I am very satisfied with the product. From ordering to installation was very quiet simple. The original cat rattled. I installed the flowmaster cat and the American thunder series exhaust and am blown away by the difference in sound, added horsepower and improved mpg.would definitely recommend!!!

1995 Tahoe Converter Replacement

I got this converter because my stock one from 1995 just wasn't cutting it anymore. The old one was rusting through and rattled, and I had good luck with the Super 50 Delta Flow, so I figured I might as well buy from the same company (made in USA is also a plus). It arrived on time and seemed to be very high quality. I installed it myself at the school's shop, but I'd highly recommend taking it to professionals...no more rattle and feels like the exhaust flows better now. I would buy again!

Not quite a "direct-fit"

It looks good sounds good but the down pipe from the left side was 2 inches too long, the exit pipe from the cat was 1 1/2 inches too long, there wasnt any bolts for the cat to the muffler pipe, and there wasnt a plug for the O2-sensor hole.

Great improvement

Was a basic bolt in, had to replace both O2 sensors, because of their age and the rust. Have seen an improvement in gas mileage.
