Ive already searched and can't find any threads pertaining to this, so here goes. Has anyone run the nismo s-tune catback and removed the resonator on the midpipe and replaced it with 3" piping to match the middy? Im running test pipes, soon to be xyz pipe with straight pipe, and want to remove the resonator on the s tune, but wanna see if anyone else has done so (im not worried about rasp). Its only about 15" long so im sure it would be cheap to have done by a shop.

I'm sure it can be done.However,its gonna be loud.
In addition,as with many guys fooling with their exhaust systems,keep in mind
Nismo S-tune(actually a Fujitsubu)is just that,a SYSTEM.There is more to
being an efficient system than eliminating components and enlarging the pipes.
You may actually loose power and gain...loud.I've got the same system with HFC's
Its comfortably loud.Just be careful.Opening up your exhaust to a certain extent
makes no sense unless you are FI.

Thanks jcity, I'm just curious if anyone has actually done this before, and are you using the nismo y pipe with your setup? I'm sure you know it is notorious for cracking high flow cats and test pipes, which is why I'm using the motordyne.

I have the S-tune and had no idea its Fujitsubu I always thought the company that makes it is Weldina judging by the badge on the muffler

Yeah fujitsubu makes the s tune and hks makes the exhaust that comes on the 350z nismo stock

the exhaust on the Z33 Nismo models is exactly the same as the stock HR exhaust except for the muffler part, so HKS makes that muffler or HKS makes the 350Z exhaust system? lol first time hearing this, kinda weird.

I had a smaller resonator on the mid pipe with xyz resonator and berk hfc...trust me... Don't do it...

So you had the original s tune resonator from the midpipe replaced with a smaller one? Did you not like the sound at all?

Rasp was unbearable at times.

i wouldn't do it. Its there for a reason, removing it will invite annoying rasp or some pinging noises.

I removed my resonator but from a STOCK exhaust system. I did it for smoother exhaust flow. However there is no point of doing that if you don't replace the cats with test pipes. If you make many changes, I would strongly recommend a re-tune. I hope this helped.

As far as sound, for me a quicker/faster car always sounds better
