Really? I've had 5 stock catalytic converters fail the same way every time: the upstream catalyst core becomes dislodged, and slides about 1.5" towards and often into the central O2 sensor which will then result in the check engine light if the core gets crushed into the sensor itself. A Fabspeed pipe has tapered ends that surround the core so it can't slide out of position like the stock system. In what way have you seen the Fabspeeds fail?

 

You are in CA I dont think it is leagal there for you to remove them.

 

That is exactly how mine failed. Interesting thought about the Fabspeed design.

 

the ones we have seen fail (100 & 200 cell designs) did not just shift the cores broke down into small pieces and start coming out of the pipe. Even with the flared ends once it starts breaking down its all over.

 

Well so is speeding. I'm through with replacing cats

That really made me laugh

 

Lol good point... One carries at few hundred dollar fine and the other a 10,000 dollar fine :x

Im not trying to be an ***, Im really just saying this may not be something you want to post on an internet forum for people to see. Kinda like posting a video of you speeding.
