i have a 87 N/A auto with 2.5 exahust pipes all the way back going to one muffler. have one precat left in the down pipe and installed a magnaflow high flow cat today.

ok so i installed a new magnalfow high flo w cat with 2.5 pipes in and out. i have one pre cat left the one on the down pipe. installed this high flow cat that was ment to be for a v8. it has the air inlet pipe too and i reconnected it using silicone hose. when i had hte holse exhaust down to weld the cat in place i also sprayed the holse thing down with paint that will hold up to 1200 degrees to slow down rusting . i test drove the thing making sure its all goood. floored and the EGT gauge showed 1600+ degrees. is that normal going about 60 --70 at full throttle? i turned the car of after letting it sit for about 10 sec at idle and then looking underneatht. i saw smoke coming from the cat. now my question is , did i melt the insides? hopefully not. it stopped after about 20 sec at looking at it.


few more qustions.
1) will the paint catch on fire if it gets to hot?or will it just come off ?

2) will the cat catch on fire if it gets to hot and will that spread?


please let me know casue i dont want my car to burn up. or me

 

if you dont let that paint cure for a couple of days it will not work right and smoke for a while maybe even burn. ive seen this happen a couple of times on headers, wait a couple of days then turn on the car it should do the job.

 

on the back of the pain it said to let dry for a hour and it will settle withe heat then. i let the paint sit on there sence sat 12 nonish and put the thing on sunday moring around 11 nish am. looked dry and the smoke didnt reallly come from the paint it came right from the cat.

i just dont want the car to catch on fire. anyone have any feed back
please let me know.

 

anyone ?

 

i was hoping some one would anser my questions cause i have to drive it home toinght and dont want to drive in flames or have the car catch on fire .
some please take a few min and anser these
someone of you out there are smart and could deff help out a bro.
thanks again.

 

I think you're safe, only because I have never heard of a cat just bursting into flames because it got too hot...If the paint is high-temp, it shouldn't burst into flames either...If it's still smoking after a couple of drives, then I would start to worry...
