    I am so glad I took this route. It was lot cheaper to buy the part on Amazon and have a muffler repair shop install it. It cost me $300 (parts and labor). A regular repair shop quoted me $800-$1200 for parts and labor.

    I wasn’t willing to pay over $1000 for an OEM catalytic converter for my 18 year old Toyota, but I also did not want to throw my $ away at a cheap aftermarket version. I have used magnaflow mufflers over the years and have no complaints so I feel like this is a happy medium. This is universal, made to fit many vehicles so I suggest you go to the Magnaflow website first and crosss reference the part number to your vehicle. I doubt this cat will last as long as OEM, but the quality and construction seem solid. Magnaflow even offers a buy back for your old cats which is a bonus for the buyer ( free shipping back to them + $) and better for environment ( recycling).

    After some meth-head stole my catalytic converter from a church parking lot in the middle of the day, this way a quick and reasonable replacement. Our van is up and running again.

    The price was 25% of a Honda replacement and since the previously mentioned "person" cut the pipes with a sawzall a few pieces from a local auto parts store fit together good enough to run until the van is retired.

    5.0 out of 5 stars OEM Grade Replacement
    Reviewed in the United States on September 7, 2017
    Verified Purchase
    Magnaflow lists this as the "OEM Grade" Replacement on their web site for the 2001-2005 Honda Civic. There is another one that is bolt on, but it's significantly more expensive. A decent welder shouldn't charge you more than $100 to weld a universal cat regardless of which part of the country you live in.

    I've purchased a cheaper universal cat before for around $80. It helped me pass emissions, but it pulled a check engine light in 3 weeks! Granted, my head gasket was leaking, which was what caused the original to go out.

    This lasted me 7 years, 84k miles before I replaced it unnecessarily trying to hunt down a problem. I got the same one again. Beats the heck out of $1200 at the dealership.

    If you need a replacement catalytic converter, I highly, highly recommend getting this one. You can get some for a little cheaper, but it'll only last you a couple of years at best. If you want it to last, get this one.

    Edit: My car has been starting to trigger a check engine line again about every 3 weeks now. It's been almost another 7 years. I did have another head gasket leak about 2 years ago, and I'm also starting to burn oil now. I think I can pass my emissions test again like this, but it is little bit annoying that i may have to replace it again, but it's for a 23 year old car. Not bad for aftermarket, and over 100K miles though.

    Had my OEM catalytic convertor stolen 1 year ago today (on my birthday) from my 2006 honda element. Ordered this cat as replacement hoping it would fit and comply with O2 sensors. Got a muffler shop to install for $150. Has been a year and it has been working amazing. Highly recommend for Honda Element or CRV. Just be sure to protect the new cat with some steel wire like I did.
