i remember there was a discussion on this a while ago but i can't seem to find it. anyway, my question is this. will a cat, stock or otherwise, survive after the installation of cams (be it single like the esslinger or a pair like crower)? if i remeber correctly the discussion pointed out that a stock cat would be toast after cams but nothing was mentioned in regards to an aftermarket cat. would it be possible to run an aftermarket cat or is an ORP/race header manditory?
will a cat last with cams?

10k w/ford 1s tuned and 0,0, cat shows no signs of any issues (comes off and on alot for ORP swaps (track days))
stock header though thats key, shorty header=dead cat. still advise a random down the road. more power.

My cat's gone at 50K.
Go-Fast mods as follows:
Intake resonator removal (in ford parking lot, no miles)
FocusSport Plug Wires (within 1st 1,000 miles)
AF/X UDP (12,000)
ITG ProFilter (15,000)
DiabloSport Performance Chip (23,000)
Other than that, all my mods are aesthetic, ICE, or handling. Intake is almost stock, exhaust IS stock.

i have an aftermarket cat (random tech), but i'm wondering if even it will hold up over time. it is bolted to a shorty header so i'm thinking that the combo with cams would be enough to kill it. if so i'll get a longtube and use the shory/random for smog purposes.
