Magnaflow Catalytic Converters - 49 State Legal Reviews


High quality at a great price.

Reviewed By Bryant H (CHARLOTTE, NC) Reviewed for a 1999 GMC Suburban —1/30/2014 2:26 AM

I shopped around for the same catalytic converters, but most places didn't have the same warranty and no one had the same low price. Once they got here, installation was as easy as you could ask it to be. The pre-fab angles were all right on, and it went on quickly. I do wish it were packaged a little better. One of the converters was a bit beat up (not enough to effect performance), and the gasket was bent out of shape. Still delighted with the deal and the product.

Bolted right on, came with o-rings too! I replaced both upstream and downstream sensors with denso. Cleared my ecu with a harbor freight scanner, smogged my car in CA. Fixed my check engine light for less than -$850! Not bad!!! Thinking of getting aftermarket headers with upgraded exhaust with the money I saved!

good bang for your buck

Reviewed By Jgru K (Flanders, NJ) Reviewed for a 2004 Chevy Silverado —3/14/2015 5:47 AM

Great replacement for stock cats. Noticed significant increase in power and good sound with Flowmaster muffler . No problem with codes from o2 sensors with new parts. A lot less expensive then stock factory parts.
