Magnaflow Stainless Steel

[Broda]

Magnaflow exhausts use T-409 over T-304 which worries me because it's got a much higher ferrous content, making it rust prone,

Anyone know what the warranty situation is on them?

AND also what is the factory exhaust system made out of?

I have a magnaflow exhaust on my wifes SRT8 Jeep and also a Corsa exhaust on my silverado truck. Both are very different but the stainless on the Corsa is better but then it is a lot more expensive. Had the Magnaflow on the Jeep for around 3 years so far and no problems and it is a daily driver all year round. What is it you are worried about rust wise on the magnaflow?

[Broda]

You can't seem to register a magnaflow product for warranty in the UK, only allows US States, therefore with the cheaper 409 being susceptible to rust it seems the biggest let down as build quality is usually good with them, and I don't want too be forking out twice, rather buy manifolds

Then if you are worried just buy a magnaflow from the UK from the dealer then you will have you warranty?
