Is it possible for an 08 350z stock exhaust to fit our 07+ G35 Sedan Sport?

Will a cutting and welding from a professional shop might do the job if not?

My friend has a set for sell, and I can take it from him for free if I put it to good use, haha.

 

It's not going to fit without cutting and welding it into a custom system.
You can make anything fit with enough time and energy, but no, you won't be able to just swap it from one car to the other.

 

Also I bet the cost of the custom job to mod the exhaust to work on your G would be right up there in cost. I think you would be better off just picking up an exhaust made for our sedans believe it or not. However it won't hurt to get some quotes just to check it out assuming the shop would be up for it.

 

Not worth it IMO

 

Oh i see, okay cool! Thanks guys!

 

I wouldn't even bother dude, if you've seen the difference between the coupe exhausts and the Sedan exhausts you'll know that its more hassle than its worth, just by an exhaust for the sedan.
