Clogged Cat on FC

[671_p5]

Meow meow...

Which cats usually get clogged? I can't rev past 5000 right now it just cuts and falls down a few hundred rpm then continues to rev until it hits 5000 again. Also feels slightly weak revving in neutral.

they can all become clogged. The best bet is to replace them all w/ a straight pipe but if you need legal emissions an exhaust shop should be able to get you set w/ a new cat and pipe

so go to triple J mazda and get them to replace it under warranty

 

[evilmonkeyMSP]

how long is emissions equipment on these cars covered?

cats have a nationally required warranty of 50k i think. some states require 80k.
in theory they always say that they should last 'the life of the car' but with a rich msp and since its not that true anyway, it might not happen.

good thing we're talking about RX7s, not MSPs

ahaha well one of my plugs is missing a boot. The second rotor trailing plug. I've been told it could be arcing to the block so ill try to cover that temporarily for now and then ill try running open cat if that doesnt fix the problem.(uhm)

What gen RX7 do you have? Running a midpipe on an FD carries some significant risk.
