Question can the kinetix high flow cats be used on a g35x with stock exhaust? Just wondering if anyone knows this. Want to get some gains now until either stillen or borla come out with a exhaust system.

 

I don't think the X uses headers and cat's that are different part's then the RWD G's and Z's do. Perhap's a trip to the dealer's part's department is in order to quiz them if X and RWD sedans have different part numbers for the cats is no one come's foreward with anything else. I know the X is different down stream of the cat's for sure.

 

Thanks for responding. Will do.
