E30 Zone

what is everybody running mine has a scorpion on it. but it looks like its been squashed under the rear beam where its been fighting with the floor lol

alos what types of tail pipes are people using as the bumper has big cut out for twin exhaust tips

This is whats on my cabby at the mo but it will be for sale soon as im opting for custom stainless steel powerflow unit on 20th june.

custom straight through exhaust.

made by 'Vortex Exhaust Systems' in thurrock

awsome what does that sound like! no middle section? just a back box?

Scorpion with STW tailpipes

Mine sounds like deep on idle and a double type noise as you cruise but the new one will be to my taste im gonna have it deep not boyracer loud, i have a middle box but the baffles gone so im goin custom i cant wait!!!

Mine...

I got a Bosal exhaust which came with the vehicle. It is blowing slightly and not mounted the best but sounds AWESOME especially in tunnels, narrow streets, next to cars on your right for some reason as it reverbs off them.

does yours look like this .. lol

whats the reason behind the two pipes anyway y not into one pipe?

i think it is just styling. From a fluid mechanics point of view all it does is the bigger the exhaust diameter the slower it flows out of the exhaust and vice versa.

Think of a venturi tube.

Yes, thats normal

There crimped to help clear the rear beam.

I got a scorpion lemans fitted to the cab,sounds lovely..

mine currently looks like this.....



hidden FTW

scorp le-mans ftw!

mine






i would personaly stay well clear of powerflow,they are utter shite ,in my experiance.

Full BTB manifold and sysytem -

ohhh them last two systems look amazing! surely having the pipe crimped cant be good for airflow lol.

im just wondering with the twin pipe idea is this because they need alot of back pressure?

the above e30 looks amazing full stop

Not got a pic at the mo, my 316i has a manifold back stainless system from longlife, de-cat, centre box is still there but just an empty resonator box and a 3-3.5" inward rolled pipe. Will try and get a pic up asap.

BTB3 manifold with longlife stainless the rest

And she sounds like this

I have a peko backbox which is so delightfully chavtastic that my MOT tester has given me an advisory for a blowing exhaust 3 years running just to cover his arse.

I've got a Powerflow system...custom built by TopGear in Aylesbury...





My old 325 had a Magnex SS system, but the centre box was a poor design and was eventually replaced (after several failed repair attempts) with a OE mild steel one...

Julz, did you ask them to make the system like that?

I think it looks awful.

Powerflow do make 'twin out' rear silencers definitely tidier IHO, I picke my parts and got them to put it together for me.

My centre is 170 oval by 500mm 2 & 1/4" single in and
my rear silencer is the 170 oval 390mm long (not advertised in this exact length anymore), 2 & 1/4" in and twin 1 & 3/4" out.

Not on a 6 pot but my down swept tip on my home made system, i just bought the box with no tips on from a local custom exhaust place and made the rest from the manifold back.

Also sprayed the back of the back box with black VHT paint so its doesn't stick pout like a soar thumb

My original back box was absolutely finished when i replaced it with this :

Well:
I asked for a system to a) be under 95dba @ 1m 45deg to comply with most trackday noise tests b) to retain the x-pipe and c) not be too boomy
The twin outlet box they originally tried was too loud and a bit too boomy...hence the use of the 2 single boxes...

From the rear it looks standard (ish) and is well made and fulfills all the other requirements...

looks perfect how much did that set you back

as above murphy how much was that did he fit it aswell im looking for a manifold and downpipe upgrade at some point since i have a stainless from the downpipe back now. . . .

this is my custom exhaust, originaly done for my m50 but now i have the m52 blowing through it

My scorpion with custom STW pipes. 3mm wall thickness on the tail pipes rather than the std 1.5mm
