    It was a bit of work getting the system to fit on the 45. The overall compatibility I'd say was 90%, with 10% custom work needed (cuts, bends, and welding here and there). I have to say tho that as of right now the nismo exhaust on the fx45 does NOT sound the same as on the fx35. I thought the overall tone of the exhaust would be the same but only deeper than on the 35 but it is not. However, it is definitely throatier. My first impressions are as follows:

    1. Less but deeper rumble at ignition
    2. Tone is a bit higher in pitch but has deepened with time
    3. Overall sound is different and very noticeable and aggressive on load
    4. No immediate or long term torque loss noted

    Also, I have not yet added UTR y-pipe so that may also change things. I wanted to add one variable at a time to see and feel the changes.

    Note: With the addition of the 3in UTR Y-Pipe and the G35 extension piece the exhaust system seems to sag at the connection point of the two. So there was a need to add a extra hanger in that area for added support.

    Compliments the nismo exhaust very well and gives a much throatier note and seems to free up the exhaust a lot more. Highly recommended!

  2. Other than the differences in sound, is there any difference in performance that would be noticed when you step on the gas, or is this a mod that just makes it different from stock?

    You will gain some top end power due to the larger 3in Y-pipe and exhaust. Plus I think it sounds much better then the oem exhaust note.

    1) It's Nismo!
    2) You're tuned w/ Technosquare
    3) It was made for a 3.5L V6

    I could be wrong but I have a feeling you didn't lose anything! If the company made this and it was for a smaller displacement of 3.5L V6, I think you would only gain from adding it to a 4.5L V8, especially since you got it tuned.

    Either way, whatever gain/loss, the sound is awesome and who else has a Nismo exhaust on a FX45 (or maybe you are the only one?)!

    Brand new right now about $1,200 on ebay. But from a online retailer around $,1,500. The best way is to look around for a used system on the 350z forums.
