F355 Active Exhaust system

[OlberJ]

Hi folks, i asked some questions on this a while ago but i cannot find the thread.

The F355 system works with 3 inlets, 2 which are utilised all the time and a 3rd which comes in above a certain rpm and 3rd gear upwards IIRC?

What i'm interested in is where the "valves" are on the system.

Are they located in the mid section of the exhaust? They open up the butterflies and allow exhaust gasses into 2 new pipes that y-merge and then enter the 3rd top inlet?

So essentially you have one bank going to one lower inlet, one bank going to the other lower inlet and then the "screamer" y-pipe which comes off each of the aforementioned mid sections?

Or is the active butterfly/valve actually in the backbox itself?


Any info would be very much appreciated.


Cheers,
Olie

Any suggestions where i might be able to find this info?

The butterfly is located at the end of the Y-pipe, just before it goes into the upper section of the backbox.

HTH.

Perfect mate, thankyou.

I believe Capristo make a switchable system if thats what you are looking for.

Ring Eurospares before you take a hacksaw to your exhaust!!

Ah, fret not, its a standard system I have fitted to my 3.0 Mr2. I'm only using the bottom 2 inlets, 1 from each bank.

I will plumb in the 3rd inlet and see if it gives me more volume under load. If its too loud ill add a switchable butterfly too.

The exhaust only cost me 25quid so not shy with the grinder and welder

An in joke surrounding the Veranti?

[Jonty355]

No, just that you had people thinking it was for a 355.

Is this for the new Dino replica based on the MR2? Saw that on the Kitcar thread, looks very nice! If you get one, please get it done in gaillo fly yellow or that light metallic blue they used to do them in! Not fussed about the colour they used for the demo car.

[OlberJ]

As it is at the moment : http://www.youtube.com/watch?v=IVkqCFhO-k0

It will indeed be transferred over to the Mk2.

And yes, it was a standard Toyota colour that the demo car is in. The shell i have is this colour though :



So the car will end up a bit darker.

Does sound pretty quiet. Is that the 355 exhaust on that you say?

You tried the mongoose exhaust for the MR2? I had one on my Veranti that would sound nice for a Dino if thats what you're doing? And that was just a 4 pot.

Go yellow!

[OlberJ]

The quality of noise from the 355 system is better than any others i have installed, i'm just interested to see how it sounds using all 3 inlets and if that sounds better.

I do like yellow but i'm building it for the old man, and he prefers the grey.

[Jonty355]

At least try and get him to go for this if not bright yellow!:



Just cant see grey looking very good. Will be obvious its a replica and look cheap IMO.

[OlberJ]

I dunno, that looks pretty nice to me.

[OlberJ]

or even

[Jonty355]

I stand corrected!

Still not as nice as yellow though!

Where were you when I owned my Veranti btw? Was always tempted with the V6 conversion for that as it was a bit underpowered, and I'm not a fan of turbos!

[OlberJ]

Been around for many a year. There was a lad on TwoBrutal who has a Veranti in a dark blue. Pretty sure he sold it on.

Seeing as it's quite feasible to fit an Audi V8 lump longitudinally in an Mr2 now, that would be my choice.

This seems a very sneaky way of getting replica/kit cars discussed and by implication legitimised in the Ferrari section
