I'm getting the AWE Touring Exhaust installed with AMS Full Catted LDPs, and would appreciate more info on the "shims" solution your installer used, in the event the rubbing issue emerges.
I feel very much the same. One of my first cars was a ’72 240Z, back in 1978. At 16, I was the talk of my peer group—it was something special. A couple of years later, I had another ’72, but as life progressed, practicality took over and I could only manage one vehicle.
Like you, I found the Z...

Hi all, thanks for your comments. Very helpful.
I'm going with your recommendations and adding a heat exchanger to the pkg. Going with AMS.
Tuner agrees that catback likely only add 10%, and i want to retain factory sound, so leaving for now. Though I am open to systems that improve exhaust...
You are correct. I looked deeper, and the Wheel HP/TQ numbers would be less on 91/93 pump gas. Overall, it's looking like my pkg would amount to about 90-100 hp and 150 tq gain.
As per ChatGPT:
Stock is an official factory crank rating for the 2024 Z NISMO. 91 and 93 octane figures are...
Thanks. Funny. I almost went with Mishimoto intercoolers, but read they didn't cool as well as AMS on repeated pulls. Though, I admit that I liked the the idea of AMS continuity in my package.
P.s. I watched the Mishimoto intercooler Z installation video...impressive kit.
Nice! I see that they charge $5k USD for pkg only on website. I guess I am going with my version of a pump gas version - 91/93 Octane (hence no fuel delivery related components), and intercoolers rather than heat exchanger, with full catted downpipes instead of lowers only. Being a new car I am...
It maybe. However I reran Chat with OEM Performance/Nismo exhaust and talked with my local tuner - the 5-10hp gain estimate holds. Where the big difference would be in applications with upgraded turbos with substantial airflow increases and output targets well above 500 hp.
WHEN CAT-BACK...
Hi all,
Here is an ChatGPT summary of my final decision on upgrades:
Redoing it properly:
For a 2024 Nissan Z NISMO, Nissan rates the car at 420 hp and 384 lb-ft at the crank from the factory. In wheel terms, a stock NISMO typically lands well below that on a dyno because of drivetrain loss...
Very helpful info thanks. Almost 3/4 of an inch for both front and back. Wondering if anyone has actually tried that or other wider set ups on stock suspension and camber?
