Okay so I was installing my nismo today and came across something. I had bought 2 extension pieces (knowing I only needed one) from someone locally. They said they bought from mynismo.com. The thing is, I've read that the extension piece goes between the Y pipe and the midpipe. The one's I receieved make the exhaust fit fine. However, 2 are needed because the flanges arent wide enough to fit the nismo exhaust between the midpipe and the y pipe. So...here's the deal. Right now, I'm waiting on my nismo y pipe...so I installed the nismo exhuast with the stock y pipe. It goes stock cats-g35 extension pieces on both sides-y pipe-midpipe-muffler.

Will this work okay, will it alter the sound or affect performance any? I mean the exhaust fits okay, sounds quiet-which I assume will be remiedied when I get the nismo y pipe..but I'd appreciate some help with my questions here.

Summary:
1.) Location of G35 Extensions-will this work okay?
2.) Will replacing the stock G35 y pipe with the nismo y pipe alter the sound with the Nismo Exhaust.

Thanks very much in advance.

 

1. it will work, but you should put them where they belong.
2. Y pipe isn't going to change the sound very much. you'll notice the sound change at start up but then it will fade to stock again.

 

Okay so its fine for a while to keep those 2 extensions? And darn I was hoping it might be a little louder with the nismo y

 

you'll be find, but if you feel your car lagging.. just check for an exhaust leak, cause I doubt you put gaskets at both ends of the extentions?

Nismo Y would be a little louder.. but dont expect it to be the difference maker.

 

Yeah I put gaskets in...I do have a small leak near the muffler but I doubt that will make a difference so far away from the engine
