How to tell if your cat is clogged?
Hi!
Was wondering how do i tell if my cat is clogged? My mechanic was saying not much was coming out of my exhausts. He said he can take off my cat and check it sometime next week, but if i know how, maybe i can save the trip and check it myself. What do you look for in a clogged cat? How do i know if i need to replace it? I do notice the car is feeling kinda slow these days and the exhaust sounds kinda softer.
Also which cat should i buy if it does need replacing?
I heard of ETD racing metal bore cats or should i go with the flyin miata cats? Which is better? Why? The one i have in the car right now is the flyin miata one.
Thanks!

yes i do feel teh car slower
but how do i kno forsure when i take it out, what do i look for in a clogged cat?
i heard that if the car is runing too rich or lean can also affect the life of the cat and how often you redline the car.
and once i find out if i realy need a cat, i need to know which one is the best out there for my miata.
thanks!

when my cat broke and keep clogging itself, it would start to fall on its face, going up hill or if I gave it more then 10% throttle. Mine broke, as a sold mass and was blocking the flow.

Granted this was on an N/A car but they showed that all the cats are about the same even between the universal cat and flying miata cat.

Erm, try to see sunlight through it. If you can't, it's clogged!
Alternatively, you can get a bag of sandblasting media and pour it into the throttle body with the engine running. If it doesn't come out of the tailpipe, the cat must be clogged. It's also good for polishing the airways inside the engine, or so I've heard.

Yes! Only 1hp was lost when the cat was bolted on! The dyno chart looked almost the same. I was shocked!

hey guys
yeah we jus took out the cat and put in spikes extra test pipe lyin around
the car maybe feels a bit faster, but my car still feels slow...
before i was at 13psi, i boosted to 14 psi and the car feels slower after tuning, could it be a bad tune? Seems like the power doesnt wanna come out of my exhaust. I have flyin miata dual turbo exhausts on my car. Another thing we installed onto my miata before tuning was a dual feed fuel rail from tunertoys and a mac valve solenoid from the gm solenoid. We have no idea why im making less power! :S
