Im looking into changing the mid pipe on my g37x sedan. does anybody know if its different between the x(awd) models and rwd models? looking at an hks because i have the HKS mufflers and need a bit more noise. the full cat back is only sold for rwd models and not awd. the only main difference i can see is the mufflers but im not sure exactly.

 

I have the HKS tips as well and would like to pair them up as well, the HKS catback your talking about , is made for the coupes not RWD as you stated .....theres actually a few options, google G37 sedan mid pipe....I think the problem youll run into is where the tips "plug in" , probably gonna have to have some work done by a muffler shop to connect the tips to the mid pipe
