I've posted this in the G-spot bc it includes both V35 coupe and sedan owners or others that can shed light on this mid-pipe. I got the following mid pipe locally from a G35 coupe driver and was told it was a nismo pipe. It has an extension welded on the front and I assume that's bc it was 350z to G35 swap originally. Didn't get much else from the seller as he was not present when i picked up the middy.....but he said it will fit my sedan fine.

 

yea its the nismo mid pipe. you'll be fine running this.

the sound of the nismo exhaust is perfect imo.

 

Thanks I'll be installing it on my sedan. I was unclear bc it doesnt say "nismo" or nissan anywhere on the middy.

 

One thing I noticed it that the extension welded on is about -1/2 in diameter smaller than the pipe itself...What were they thinking? I'll prob have the shop weld on a proper 3"
