Since the Magnaflow 23120 replacement is only $400 less than the $1400 OEM pipe/cat, I thought I'd ask, has anyone used these, and what are the thoughts after installation?
It wouldn't be a stretch to guess that the price difference is in the metal.Don't have any experience with any of the aftermarket Cats but it's been discussed before that the non-California approved Cats may not have as much of the expensive metals (Platinum, Palladium, Rhodium) in their matrix compared to California Cats or OEM.
Wonder who's had one of these aftermarket Cats on the longest (miles/years) without a Cat inefficient code?? IDK
I installed them on mine about three years ago. Mine are the aluminized steel version, not 409SS.Given the numerous reported fitment problems at the headers, and the fact that no one has reported actually needing to replace the y-pipes, has anyone successfully replaced only the front cat?
Deal!Try hottexhaust.com. I believe it is a Magnaflow store and they have a 20% off offer.
