Just wondering, How many miles do you have on your cat with turbocharged setup. I got about 10K so far,

while n/a, high flow cat lasted about 40K and was half hollow on the inside.

 

searched to fine some answers again.. and looks like this is the only topic on this..

i'm at 18k boosted miles now with 2.5" carsound cat.. and i don't know when i should look into replacement.. i don't have any rattles, it runs fine as far as i can see.

 

anybody else running a cat with turbo?

Just wait until it gets clogged up. Then I wouldnt even replace it just hollow it out!!!

 

how much would my a/f ratio change if cat was hollowed out or replaced with testpipe?

 

I had a test pipe on my car then I kept getting check engine lights so I had to buy a High flow cat then found out that it was my map cen reading boost. I could tell a big difference in hp on the butt dyno so now that I have the map cen fixed with a better check valve I want to put my test pipe back on.
