Alpina Exhaust - interesting info

[M5pilot]

Just been speaking to BTB about different things and one of the topics was exhausts systems.

He used to own an Alpina C2 2.7 a long time ago and he took the exhaust apart. He said it was a very very clever design which increased power.

He then went on to tell me about C2 owners coming to him who had changed their Alpina exhausts to after market systems and complained about power losses. He also mentioned how people working at Syners said it was more or less like a standard system and gave no real power increases.

To summarise, the Alpina exhaust has huge bores and is a straight through system which had very clever chambers inside and it apprently sounds amazing.

When I said to him not alot of Alpina's make the power he said its because they lose their exhausts and their 6 branches which could easily chop off 10-15 bhp.

We also spoke about Scorpion exhausts and he said they werent very good for power increases and only made that noise because they were so hollow.

He then went into to some technical stuff which i didnt really understand too well but it was about bore sizes, X pipes, air scavenging and stuff that just went straight over my head.

Asked him about if he could make something like that but even better and he said yes but it wouldnt be cheap - Ԛ£800 or so.

I thin Hap is getting one imported from Germany, might have to speak to him about this!

But there you go anyway, Alpina exhausts were the best out there and did heavily contribute to the 210bhp claimed figure. My one lost a fair bit of power and torque when i fitted a scorpion from the quicksilver system.

[Turbo-Brown]

Are Alpina systems still available?

Might solve my exhause problem (assuming I could afford one )

[Karan]

didnt u get those quiksilver ones made to same spec???

[Andy335Touring]

I'd love a B6 exhaust but it would be a lot of money !!! (1000-1500 quid ???)

I want to change my Scorpion M3 exhaust as it's a bit loud for me.I was looking to replace it with a standard M3 exhaust from Ebay but i got out bid in the last minuet.

The bloke selling the M3 exhaust said the bore size was 1 3/4 inch which will match up (ish) with my E34 M30 down pipes but i've baught a 6 branch manifold from an E34 Alpina B10 and the bore size is 2 inch's so i don't know if the M3 exhaust would have flowed enough for what i want.

Sal mentioned X pipes and i had a look in the ETK at the E30 M3 and E34 M5 exhausts.Both have X pipes just after the join between the manifold and the exhaust,my Scorpion M3 exhaust doesn't have an X pipe and the Scorpion exhaust has a bit of a reputation with the E30 M3 boys for losing them torque.I'm guessing it's down to the lack of this X pipe.

For people who don't know what an X pipe is have a look at this picy.



I'm not sure what to get to replace my exhaust now,i will have to save some pennys for a custom exhaust i think ?

uve gotta be funny in the head to spend 100-1500 on an exhaust

[M5pilot]

The Alpina exhaust is over 2".

Quicksilver did make them and they want Ԛ£500 for them

They say they are an EXACT copy.

They are shed loads better than Scorpion exhausts and they dont blow out their insides like some people suggest.

X pipe is very important, does increase torque a fair bit.

[Andy335Touring]

I'm guessing the Quicksilver copy was of the C2 exhaust ?

Are they still available ?

I was estimating the bore i'd need for my M30's exhaust by measuring the Alpina B10 manifold.

[Hap]

Yes Sal the Alpina exhaust is fitted and is rather quiet IMO, but hey its mild steel, Simon Alcorn has fitted the quicksilver on his C2 and i tell you the noise is something else...amazing! Sal the car does feel more responsive after i took the other piece of crap off, i fink wiv more use the alpina exhaust will evetually sound even better

Andy i have the quicksilver exhaust for sale brand new, never fitted, u cud come down and have a look as ur not too far from me. Yes it is an exact copy to the tee wiv all internals the same but using modern materials for the baffles, exact tail pipe design 63mm and the bore througtout the system is 50mm i believe

pm me for details as i need to make some space!!

yeh scorpion centre sections are really crap!---im just gonna get mine removed and straight pipes put in.....

[M5pilot]

Karan, dont do that, youll lose power.

Hap,

I spoke to quicksilver and Paul said simon got it made so exactly its unreal.

Paul also commented on how complex the alpina system is inside and how much fabrication they had to do. I did tell him off for taking so long though!
Anyway, thats both BTB and Quicksilver who have said that this is one hell of an exhaust and would be dificult to beat.

I'm very interested in buying this exhaust off you Hap. Give me call please.

Looks like you were right all along!

oh and theres a stainless c2 system in bmwcar this month for Ԛ£400odd

[M5pilot]

sound awesome? Haps car had straight through pipes and you couldnt hear jack!
My M3 had straight through pipes and again......you couldnt hear anything unless behind the car.

You run the risk of losing alot of bottom end torque aswell.

[Simon13]

so is my system pants then? i know it's not exact alpina cos the tail pipes are too small, plus it's made of monkey metal. Sounds sweet tho, should sound better when i get my magnex 6 branch on i hope

[Nostrils]

I have read in many books about the E30 M3 and its exhaust. BMW created this exhaust with max. power extraction using the X pipe and creating the exhaust to the exact length required and for use with the production manifold.

The books state that the exhause with a cat (like mine) only loses 5bhp over the standard without cat. The only aftermarket exhaust that I have ever purchased that I thought was worthy of the exhaust note, construction and certainly not lacking in power was Janspeed System (particularly Ford Capri, XR4i and RS Turbo 2) - I fitted one of those drainpipe exhausts to my Turbo MK1 and always thought that it was not quite right!!

My car has 128K km and is still on its original front section with CAT. I have toyed with the idea of replacing the exhause with a Milltek, but I think I would end up going the BMW route despite the cost!

I am gonna have to wait for my exhaust to go first...waste not and all that.

As for the Alpina systems, they do sound amazing and certainly have a note of their own, definitely not tinny or raspy, very thoaty!!

[Hap]

sooooooo anyone else interested in my alpina/quicksilver exhaust?

[Andy335Touring]

You've got mail

My offer stands mate.

Cheers

[novakiller]

taking all that into account of what u all just wrote if u put an alpina rep quick silver system, and 6 branch what power out put would u be looking at on a decent lump thats knokin out say now between 160bhp and 170bhp? oviously u wouldnt get 2 the 210bhp of alpina koz of all the other stuff, av got a scorpian on mine, but reading what av read is that a better system than the original bmw system?

[M5pilot]

It would make some difference on a standard car.

However if you also mapped the standard car with those bits it would certainly make a differece.

It would then facilitate all future mods and just make them more effective.

You also get the noises!!

[novakiller]

would it be any thing like my scorpian as i do love the loud noise!

[Hap]

ok guys anyone have any questions can call me 07971 285620, its easier than explaining on here...

[M5pilot]

Scorpions dont sound anything like these things.

This is a proper noise and something that does help gas flow.

[Simon13]

so if they have a 25 year warranty then i better get on the blower cos mine has rust!

[orangecurry]

I'm confused - how many do they make?

I just asked for an exhaust, and Quicksilver said

That was exactly their words copied out of the email they sent me, so there you go..... give them a call. How long ago did you buy yours Simon?

[M5pilot]

Simon,

worry not, I have argued with this guy before and won every time.

There is a way to deal with him. He is very scared of losing the reputation of the company.

Just tell him who you are and where you come from (e30zone).

Tell him you know Salman and a guy called Simon who had an Alpina exhaust built from him not so long ago.

He will remake your exhaust.

If you need any help let me know. I paid for an Alpina exhaust just like Hap's one.

It is only now that I find that he supplied me with a "SPORT" one. What the hel is a sports exhaust???

I then sold this to you thinking it was the real deal and its obvioulsy not.

F8ck this, I paid Ԛ£500 for that and you paid not much less.

Lets get you what you paid for.

I have seen pictures of the new exhaust and its nothing like what youve got.

Give him a call and see what happens. Try not to lose your temper though........

[Wilson]

ok guys anyone have any questions can call me 07971 285620, its easier than explaining on here...

Below is an email I got from Hap, and some pics, explaining his exhaust for sale....................

________________________________________________________
Hiya Marc, its Hap of e30zone. Attached is pic of exhaust, the other one is my mates alpina one (the older looking one) to show that both are the same.

Mine is still in the wrapping hence the reason I have sent u a picture of my mates which he has fitted to his C2 (mine is identical). Basically you will need to get the Ԛ“down pipesԚâ€a made up to marry up to ur manifold. I presume you have a 325i? Simon13 who has a lachs silver sport with alpine wheels has this exhaust and is very happy with it if u wana pm him to check. It will be easy for someone like poweflow of some exhaust specialist to fit.

you will not be disappointed, the noise is unique more like a 24v car. Better than scorpion or any other exhaust on the market now I would say

I can assure you this is an exact copy of the genuine alpine/Boysen system to the exact Tee, the pipes are 50mm (standard BMW 45-48) as specified by Alpina, the internal baffles are the same in every way and the rear tail pipes are 63mm (standard BMW 60mm) again as specified by alpina in mirror finish.

The reason I am sellingԚ….i have bought a genuine mild steel alpina system for my C2.

Look forward to hearing from you
_____________________________________________________

[M5pilot]

I think I will be buying this for sure now.

[Hap]

Have you spoke to the people like we discussed?

[M5pilot]

No, not yet. Will talk to them soom.

However, I want the exhaust. Its a bit of a bargain to be honest seeing as a Scorpion costs the same and is no way as good.

Sal
