Magnaflow Catalytic Converters - 49 State Legal Reviews


colorado cat

Reviewed By Reginald R (Beckley, WV) Reviewed for a 2011 GMC Sierra —11/30/2011 11:27 AM

Had to purchase a new exhaust manifold/catalytic converter for my 08 Colorado due to a cracked exhaust manifold. With a new O.E.M priced at over $600 and a Magnaflow just a bit more, of course I chose the proven leader in performance. Along with the Catback system I also installed, I can definately feel a difference. Seems to have more horsepower and quicker throttle response.-

Outstanding Value and Performance

Reviewed By Edward Z (Mays Landing, NJ) Reviewed for a 2004 GMC Sierra —8/11/2011 8:44 PM

This converter was a drop-in installation. Once I acquired a deep socket and a socket wrench entension, the installation was a breeze. Total installation time was less than 1 hour for this disabled shade tree mechanic. The hardest part was the removal of the O2 sensor. After driving for almost 2 weeks, I have seen a marked improvement in mileage. Granted I purchased this car used, the EPA highway estimate was 26 mpg, but on a recent trip, I ran over 32 mpg consistently! For a 10 year old car, I will NOT sneeze at this economy!

1995 Tahoe Converter Replacement

Reviewed By Steven C (MANKATO, MN) Reviewed for a 1995 Chevy Tahoe —1/11/2015 9:19 AM

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!
