Ummmmm, my bro has an 07 g35 and I have an 06 350z... we both had our cats replaced with race pipes... I need to put my stock cats back on, but there is a big problem.. they both look exactly the same............ would there be significant problems if I put his g35 cats on my 06????????????????? yes, I know, we are dumbasses...

 

Hmmm... judging from what you've said, particularly that last line, I'm afraid I have to give you bad news. If you put the G35 cats on your car, you will void your warranty and possibly damage the majority of your exhaust system beyond repair.

 

they are gonna be the exactly the same you shouldnt have any problem

 

No problem. same $hit

 

 

lol, good stuff. Getting them undone from the header is a *****, if you had the test pipes installed professionally your in for a ride.
