The old cat in my 1998 Chevy K1500 was pretty plugged. This is a super awesome product.Symptoms my truck was having that this product fixed: Fixed my P0420 check engine light. Improved performance and acceleration (previously, I would have to hold the gas pedal to the floor just to barely keep up with traffic in town) Overall top speed on the interstate improved from 65mph to 80mph Highway fuel mileage improved from 9MPG to 17MPG Fixed rough idle Fixed rattling noise under the cab (honeycomb in old cat had broken loose)InstallationThe installation was a breeze. It was a direct fit for my 1998 Chevy K1500. No cutting or welding was required, simply unbolt the two exhaust clamps and change it out.Overall I am very satisfied with this product. I would definitely buy this brand again.

I Installed it on my 2001 F250 with the 5.4 triton. It was a good easy fit and way cheaper than the factory OEM. I would definitely buy it again if the need arises.

Used two to replace stolen converters on 2010 Silverado with a 6.0. no check engine light after 5k miles so I think these are great. Tight spaces welding these into this truck, expect to tack them in place and drop back out to do final welding.

MagnaFlow products continue to provide improved performance and great sound and this cat is no exception, my '03 S10 ZR-2 gained noticeable power and the sound is simply captivating.....it's not louder so to speak just more throat and when it winds out a bit it has a very capable sing to it......I have 2 identical vehicles one with Magnaflow front to rear and the other OEM/Walker.......put your hand over the tailpipe and tell me that the Magnaflow isn't moving far more exhaust idling at the same rpm. Mpg goes up, power goes up, sound at operating speed only slightly more present and my engine is happier!
