Which Exhaust ?

[Wo:Deep]

Shaun,
Yours is louder than mine !!
I have read that the Blitz Nurspec are loud and some of the Kakimoto (spelling may be incorrect).
   

Hey Chris
I have the Kakimoto R - exhaust on my Rx-7.


It is 80mm straight through. Sound is nice and deep but not too loud. (90dB up to slightly over 100dB on WOT + hot exhaust!)
Exhaust flow seems to be really nice. The Greddy titanium exhaust (also 80mm) which was on my Rx-7 before had no advantage in performance. But was a lot louder!

Keep in mind that you are pushing out 190hp more than My Rx-7 does. So maybe there could be a difference in performance. But idk.

+ The Kakimoto exhaust seems to keep the flames back a little bit better then the Greddy.
I just throw a few flames when I´m driving 270km/h on the autobahn and then go off the throttle:Thumbsup!
So you don´t have to have fear about a burning backend:Giggle


Good luck choosing the right Exhaust!

kind regards Marc

Many thanks for your information guys.
 
I would prefer to avoid having a mid silencer, if possible.
 
I do suffer from a burnt rear apron around the exhaust (I\'ve added an aluminium plate to offer some protection to the fibreglass).
 
Does anyone have experience of the HKS range ?
 
Is there a manufacturer, or type of exhaust that is not suitable for the RX7 ?
 
Thanks
Chris

I have a Kakimoto 92db:
 
 
 
It is 75mm straight through (with a silencer and silenced back box) It\'s very quiet on idle and at low revs but makes a very angry bark (I think it sounds like an old 70s muscle drag car) when under load. I have nowhere near as much power as you so I have no idea how suitable it might be. I can tell you that no-one who has heard it (other than me :rolleyes:) likes the sound of it.

that was my old back box! i loved the sound of it! the other half didnt!

[mattfduk]

making that power have you not thought of one of pips back box\'s?
very good sound not too loud and not too quiet
and most important lots of flow!

i got a kaki on my fc, only rear section n i love the sound of it!!! could do with being bit louder even though my gal can hear me come home when im round the corner (we live on 3rd floor also)

few others i met at london run also like the sound of it.
i know u got an fd, not sure how much diff it makes.

build your own, thats what a few of us have done, using 4 inch all the way through. The more free flow = more power. We all run 4" 100mm systems

Hi AshRX,
Did you go to someone like Powerflow to build the exhaust ?
 
I would certainly have to have a remap with a custom exhaust.
 
Thanks
