Had this discussion with a buddy tonight, if you took an exhaust from a non-turbo car, say a 350z, could you use it on the FD assuming an exhaust shop would bend it to fit the FD? Just curious, he asked me this question and wasnt quite sure, thanks.

 

yeah, aslong as the dimension are correct where the muffler hangs. The 350z mufflers will definately not fit though. It's long, and is designed differently.

hmm interesting, im sure you could cut the piping and re-weld the hangers to make it fit. How much of a role do you think a muffler plays in the sound of an exhaust? Is an HKS exhaust designed for the fd and an exotic cars muffler going to sound that much different?

 

There are a lot of aspects that you need to take into account when it comes to the exhaust note.

two engines that are the same displacement, but maybe one has a longer stroke and a smaller bore, are going to sound completely different. Firing order also makes a difference, as does engine type(4-stroke piston vs 2-stroke piston vs rotary vs radial, etc), as well as the size of the piping, any resonators in the piping, cats(if any), and each bend in the pipes changes the sound.

So, in short, if you took a muffler off of an FD and put it on a 350Z, it would sound completely different. Mufflers are just one piece of the puzzle

 

It depends what you consider non-turbo, if your talking about an oem non-turbo muffler, sure it would fit but I'm sure it would restrict the hell out of your exhaust, and you really don't want a lot of backpressure especially in an fd where it has naturally higher exhaust temperatures than most. Now if your talking about an aftermarket shouldn't be as major of a problem as most are free flowing anyway.

Exhaust tone from a rotary in my opinion doesn't really change at all from one exhaust to another, I have heard all sorts of different mufflers on these cars and to me they all sound the same, the engine noise is pretty distinctive, even when you put ports on them, they sound similiar but a little more aggressive and louder. Now if you get exhausts that were pretty much engineered around changing the tone it might change the tone but from my experience it really comes from the engine itself.

 

+everything said above.

Basically just because you change the exhaust to another car's exhaust, will not make your car sound like the other. We have rotaries, and will always sound like a rotary.

 

Exactly.

If it was that easy, id get a ferrari exhaust so my car can sound like that. lol

But ill stick to the buzzing lawnmower for now.

 

or maybe a 2JZ exhaust note in the future? LOL i think me and you are the only pro-mkiv people here I obviously knew that putting a ferrari exhaust wont make it sound like a ferrari, as its based on the engine, but just how big of a difference a muffler can truly make.

 

my friend has a z and i know for a fact that there is no way that it will work

 

A muffler can make all the difference in the world. Look at all the different brands and all the different sounds you get just on our cars. Everything influences the exhaust note from start to finish, the turbo's add there own distinct sound just by changing from sequential to non, add a resonated mid or a straight thru and the sound will change again, and the muffler, look at the difference between the Apexi N1 duals and the Racing beat duals, change the exhaust from a single pipe to dual pipes and another sound all together, so yes the muffler can make a huge difference in sound as well as everything in between.

 

which is louder seq or non? very sorry to thread jack, i am just curious as to which sounds better...

 

Depends on if you go with the poor mans non-seq. or the full on non-seq. But for sake of argument non-seq. is louder than sequential.

thx...

and for more on the exhaust. if you went with another type of exhaust you should prob go with 3in+ that way it will still breath good. but you prob already know that

 

Why does every one crap on the sound of a rotary. Are you guys serious the sounds rotaries makes has got be one of the top 10 things I love about it, especially when you throw a port job into the mix. There is nothing that sounds better.

 

I love the sound of mine...just wished it was a bit deeper...

 

I WISH BRIAN!! lol

O how i wish. I dont mean to sound like a supra nutrider but the sound gives me chills because it means business. I dont wanna crap on this thread but just an example of what i mean.

See how it sounds soo melo and calm but when you get on it, it sounds amazing. You dont have to be insanely loud to be fast.

I remember when i went to the track, there were tons of rotary powered cars, doing their 12,000rpm burnouts, ******* loud to all hell, yet only running 11s. Then this 2JZ powered corolla wagon pulled up, did his burnout which was in complete silence except for a light growl of the engine, then pulled a mid 9 second run. The announcer over the PA was like, "WOW, silent as a mouse. See guys, you dont have to be loud to be fast". Then he started to laugh because just before that run was like 6 straight rotary runs making all that noise. I love rotary noise too but sometimes its a little carried away.

 

Supras sound coo....I like the sound of vettes more...

 

couldnt agree with you more, they have a deeper more aggressive sound than the rotary. I feel the rotary is just too raspy, and although the high pitched lawn-mower sound appeals to many it just doesnt do it for me.

i think your comparing oranges and apples their.

 

It's not okay to compair a V8 to a 2JZ sound but it is okay to compair a 2JZ to a 13B?
