i start with mine. ;)
Ciao Enzo
I think I have already told you that I like yours very much with these gp 4 exhaust and also with the two pipes!
Looks like genuine ones...do you made these ones yourself or do you have a provider in Germany?

Heres mine
Nice tone at low RPM,not loud. And a good bark with a squirt of throttle. Few pops on the overrun :D
Stainless steel cans 12in x 5in. Cones from Ebay Australia.

Just in the process of fitting a TMAP sensor in the inlet plenum, which is why the Supercharger is off at the moment. Will post some video of it running shortly:)
Mk I & Mk II cars
Gp 4 & Transverse exhausts :o

i use this parts to build them!
Stop that! You know I haven't got one :p
A couple of variations on the theme....

The single exit system on the 2.5 24v Busso is the nicest sounding car we have built & arguably the closest to sounding anything like a real Stratos with the single note howl. Carbs or throttle bodies could seal the deal!
Can you do something similar for a Corse I ??Quote:

The Gp4 version would be too loud for IVA for sure, the single exit version no problem.Quote:

Exactly the same silencers as the Gp4 exhaust shown earlier, the difference being that this one is fitted with the phase 3 catalysed exhaust manifolds which go a long way to suppressing the noise.

Nice reg. Craig.
I saw V600 STR a few months back on the DVLC web-site and was going to buy it but unfortunately didnt - I understand it was then bought by someone else on the forum (not sure who )
Love the colour too - cant wait for my body panels !!

Finally got to fit the stainless steel system I've been working on yesterday. Planning started months ago, the bits have been gathering dust for a couple of months.
It is still a very quiet (neighbour friendly) system, just a little more base tone, and a smidgen louder. Feels like it pulls a little better too.
Nice!
Strange its still "quiet". Maybe the manifolding contributes some muffling. Is it possible to play with the box stuffing?
Tim, no I don't think the manifolds are a factor, plenty of others use them in systems that are more audible than mine, as far as the box is concerned 'take it or leave it' are the options, no packing or repacking of the box is possible.
The quieter Stratos systems that I have seen/heard on cars regardless of chassis manufacturer tend to be transverse, and none straight through.
Mine being transverse, and one in, two out ticks all those boxes. The box itself is the biggest I could get with clearance between the chassis legs, on the basis that I'm maximising the possible silencing.
Funnily in its (silencer) original four cylinder turbo application the noise is both crisp and fruity, traits which are still evident in my application but not to the same degree.
I think the manifolds merging before passing through a common silencer may also be a factor, with the exhaust pulses from one bank being damped by the pulses from the other bank?
So in effect I'm trading ultimate efficiency for noise suppression. That said the old system was quite restrictive with very small pipe diameters, so the new system is still an improvement.
If my supposition is correct straight through single banked exhaust systems will ultimately always be more efficient, and in consequence (possibly) noisier, but I'm surmising.
Here is a slightly different design, Lance from OJZ Engineering built it, Zircotec coated it and Guy Croft Racing specified the tube sizes and lengths. The headers are all the same length and the tube diameter increases after the collector and at the entry to the silencers. The two 120mm diameter silencers enable me to have the longest possible pipe and meet track day noise limits.
It does sound really nice with twin DCOE45's although it is obviously not a V6.....
I must try to fit my GoPro to the rear clam to capture the sound.

Seems like there is a garage day recently in Germany !!
Just fitted the exhaust system after having it ceramic coated by Zircotec.

Ste! It's you! - but you'll have to type up a bit, cos I can't see/hear what you're saying ;)
Is it some sort of image? Won't display on my computer for some reason....
Very nice. Probably should've done mine black. The white on mine already looks dirty and it's not made it out of the garage yet!
Photo courtesy of Rhona!
I zircotec'd mine black for the manifolds and white for the tail box. Should have gone grey or black but wanted a contrast out of the rear. White does not seem to be able to be cleaned - any ideas other than oven cleaner???Quote:

Here's mine, standard Lister Bell, but a good photo by a friend at work. No Abarth sticker there anymore, I put it on as it's been on all my cars, but it didn't seem to belong on the Stratos.

Same question to the one I asked on the other thread.. is there a heat issue in the engine bay that needs something like zircotec on the exhaust to resolve it or is it mainly cosmetic? I’m assuming there’s more cars out there without the coating than with it and engine bay heat temperatures issues don’t seem to be mentioned often? Looks good tho!!
Great news for me!! ;)

Nope - self inflicted Norm.
It was following a trip into the gravel at Donington. Whilst cleaning gravel out of the car I managed to cut my hand. I then somehow bled onto the exhaust manifold in the engine bay.....
It's not proper DIY unless there's blood.
or is it just me?

The down side is that its quite loud. I have some small cats that might fit in the silencers ( Not Kittens), so not sure if this will help.
I shall wait till next month when the car is taxed and a full road test can be done.
No animals harmed in this rely
That looks great, and I like the silencers!
Re exhaust wrap, I was always warned - and found in practice - it can harbour moisture/cause rust on the manifolds?
