my cats went bad on my 2004 g35x sedan. i was wondering if i can use the cats that are off a 2005 or 2006 g35 coupe?

 

yes.

 

Good luck getting them off the car. I was under my car the other day praying my cats don't need replacement anytime soon. Maybe by the time I need them, the rust will have eaten completely through the bolts.

 

i removed mine last week in about 45 mins.. but i assume yours are much worse with the salt on the roads there in ct..

 

Looks like three mini NutRageous holding each cat to each header!!!!!

 

oh okay thanks guys

 

my cats on my 04 coupe decided to take a ****.....so i got test pipes and whole new exhaust

OP how many miles you got on your car??

 

a lot of ppl use PB blaster or wd40 on the bolts to help them break loose.

as for me? i just work out a lot

 

lol the exhaust shop i brought it to to swap exhaust put a blowtorch to the bolts, then hammer in the ratchet and then they can pull it off.

 

I should post a picture of mine HAHAHAHA

 

just don't strip the bolts!! if u do then i dunno man u kinda screwed lol

what i do is put a wrench on and then use a hammer to hit the other end of it. the quick kinetic energy just breaks em loose.

 

i went in to get my smog done on my 2004 sedan last year and it failed..ended up being bad cats..infiniti replaced them for free since they were under a warranty..8 year warranty..not sure how many miles..mine only had around 70k at the time

 

ya man i only got 80,700 miles i am **** out of luck i wish it was still under 80000 and i would take it back to them.
