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.

Questionable craftsmanship

Reviewed By Riley S (PASCAGOULA, MS) Reviewed for a 2002 Toyota Tundra —4/16/2015 12:21 PM

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.

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!
