Well, i tried to smog it with just the rear cat (magnaflow-hiflow cat), i got a HC-110ppm. I went a bought a cal spec cat for 300 bones and got that # down to 60. I finally had to take my headers and y-pipe off and put on the stock ones and passed with a HC of 11ppm. You need a 35ppm or lower to pass.

Has anyone tried to run 2 catalytic converters (one in front of the other with headers?

Has anyone experienced the same problem i had smoging with headers?

Took me 10hrs to change out the headers with stock ones, what a PIA. Dont know if i am going to put my headers back on, too much work.

 

i run o2 sims pass smog in ny all the time..

 

It wasn't with my Maxima, but to get my Camaro past, I would put in two bottles of dry gas to squeeze it by.

 

Selling the headers??? Dibs

 

Damnn that's messed up and what state are you in!!

 

Don't you already have headers? Dibs on yours if you buy his!

 

dam thats horrible! thats what i hate about this state. well there goes my future plans for headers. guess ill just stick to settling with just ye 'ol Y-pipe
