How Long Do They Last? High Flow Cats.

I just installed a Akrapovic Evo Exhaust and was curious on how long does the high flow cats last?

Roughly how many miles /kms? Or no set time?

I guess i'll know when i smell rotten eggs

You're gonna have a smell no matter how new they are. Definitely not an indication of age. There are a lot of factors which will determine life so it's hard to make a real guess.

If they are secondaries and assuming metallic core cats you should see plenty of life outta of them..cats in the primaries run hotter so shorter life..

To be honest I have run Magnaflow cats on several different cars for yrs and havent had one fail yet so take that for what its worth
