New Fujitsubo Exhaust System to be Released


240260280

Recommended Posts


It's purported to be a higher (not better*) fit to give more ground clearance which'll allow cars fitted to run lower without grounding. I think they've altered the passage around the diff because I understand it now fits with R200s (?).

If all that was changed was the resonator to improve performance AND reduce the noise levels by a large margin (99-95 is an enormous improvement), then their previous resonator was allowing too much gas-flow and sound waves along the exhaust lines. Restricting those just proves that zero back pressure aint healthy ;-) and the lines sold by the well-known Z specialist shops with no resonators are killing Zs performance whilst introducing 'drone'.

*Some machining may occur when attaching an old car. In that case the cost and claims etc can not be applied at all. 

Well done Fujitsubo....but at Yen 276480 ($2457), they ought to be pleased.

By better, I meant a closer fit.  Its a newer header and center section(new part numbers etc) and rear routing, whatever the changes are it seems to be a gain on the previous version while offering better packaging, to the previous posters question.

It doesn't say anything about r200's?

 

As you say at a cost.

Standing still is going backwards and they've evolving - good news for the fans and also the Z scene which proves it's healthy....if there was no demand.......!

its interesting they decided to revise it, after so long.

Only zstory clear a r200 or larger though.

Well, mine will being only a single pipe.

Personally I think their twin-pipe design is 'flawed' ; there is clearly visible on EVERY Z a second (albeit smaller) inverted 'U' in the front diff support bracket that was intended to allow a twin-pipe system to be fitted to every JDM Z. The twin-pipe line and twin exit muffler was an option for the L20 and L24 engines but rarely seen on other than the S20 powered Z432s.

A twin-pipe system fitting AROUND the diff is much closer to the original format but Fujitsubo have (finally ,) reacted to improve the fitting of theirs on export cars and especially modified ones which entails lowering the car and freqently (in the States) fitting a larger diff.

It's good news and I repeat, it shows that the Z scene is alive and kicking very much into its 'nearly) 50th year :-) !

That's because it follows closer the original Nissan design for a twin-pipe system.

Having said that, they sold more single-pipe systems within the JDM and export markets.

The question to be asked is what benefits are there on a stock (and also prepared) engine from a twin-pipe system ? I have my thery but let's hear all yours.:)

The twin pipe setup is something that works with an IL6, all the performance bmw IL6's have the same setup.  I guess its down to port scavenging.

should be good for upper midrange?

Could be right there with port scavenging.

Good from upper mid-range upwards in theory, perhaps logical to fit that with an S20 producing it's power and torque higher up the rev range.

Good therefore for smaller, higher revving engines. Now, is it also good for mild-prepped L28s and strokers ?

I've no idea, works on 3.2 ltr cars.

I run 3" mandrel bent all the way to the rear then split it into twin 60mm at the Reinhard muffler. 

It must get fairly warm, the tips changed colour after the first track day.

Not sure what the flow rates are when comparing 3" with twin 60mm.

That's cute - what does a Reinhard muffler cost these days ? How long is it overall and also just the 'box' please ?

Pls give me the model number and/or link. That is ideal. Not obvious from their website (do you have to order from Japan...?)

I had a set of S50B32 headers here to compare (you know why Franky) : 

38mm primary pipes (makes me laugh when people say they 'must' have 44s, 48s, 50s for their Z!) and twin 50mm secondaries.

so many variables.  the sb50b32 is a good setup though.  for that application.

Hi Sean, these are the dimensions measured roughly, excuse the diagram. Might be suitable as a big bore option for your line of exhausts.

Reinhard stopped selling them separately after I got this in 2013. A few Aus guys tried buying them but they would only sell the entire system.
