It's not an interesting post this, sorry. They can't all be winners, I'm afraid.
Anyway, I've just fitted some new 225/45/16 tyres to the M, and dont seem to be able to find what pressures I should be running anywhere- does anyone have any clues?
Secondly, I've been trying to be contact the chaps in charge of the shop over on s14power about getting hold of a complete carbon air box thingy and all required sundries to make my E30 sound, well, awesome, like (and-if I must- increase the power- not that I want that part as much as that sound, to be perfectly honest) but don't seem to be able to get hold of anyone. So, does anyone from over there also live over here and know anyone from over there? If you see what I mean.
Furthermore, has anyone tried such a thing as a cone filter on one of these cars? I have one in the garage is all, and I'd be willing to give it a go if it'd be worth it, but would of course quite like to save myself an hour of swearing and cut knucles if it's totally pointless and- well- a bit, y'know, berk-y. The car is already on the cusp of chav as it is, and it needs no help to tip the scales the wrong way.
Finally, my car is fitted with a supersprint DTM style upswept exhaust- which makes my eyes itch just typing it, frankly- but worse is incredibly boomy. Can anyone tell me whether the standard exhaust is equally as boomy? As, if not, I intend to try and track one down from the 'bay or wherever else someone on here suggests. Failing that, can anyone suggest a back box that doesnt make me sound like a Saxo is fast approaching?
Thanks in advance, apologies again for all the dullness.

Give the cone filter a go, just make sure it's getting cold air coming in, and if you can knock together a heat shield around it, so much the better.
Try that before changing the exhaust - you might find that the induction noise overcomes the boom of the backbox.
Of course, that won't change the fact that you've got an upswept DTM exhaust...

The standard exhausts on these cars is very quite, a bit too quite for some, the Supersprint you have may be the 'race' version which has no intermediate box just the rear silencer, there are/were two version of Supersprint exhausts available.
Don't even bother with the cone filter, the main breathing restriction on these cars is in the AFM, a cone filter will simply feed the engine with 'hot' air.
An alternative airbox FYI,is available from Rongineer, allows deletion of the AFM without so much noise.
Here are results achieved with this set up and UniQ. (Not mine).

Forgot to mention in previous post, Milltek are a good comprimise on sound and cost as aftermarket exhausts, only downside on these however is they are single 3" pipe to rear box, so reduce ground clearance which can cause some owners problems and there was a quality issue with crack around the centre hangers but they are covered by a liftime warranty and I believe the design was modified to resolve this.
Miltek & Supersprint don't loose power.
Problem with a lot of aftermarket pipe is they don't have the X (or Y in the case of the Miltek) just aft of the manifold.
This X is all part of the exhaust tuning that BMW spent 2 years developing which aids cylinder filling and give more torque & power. You can lose aronund 20 - 25 bhp peak power without this.
Cheers,

This looks tasty, however I haven't heard anyone using it.

Is it a standard manifold pipe and DTM backbox or has it all been changed out?

my tuppence worth:
if the engine is standard it has been well proven that the OE filter from BMW is best just will need replacing more often than a aftermarket one
I put a Supersprint exhaust on mine (mild stainless version), it was superb, loud when you wanted it to be, no resonance or booming and quiet when cruising, even popped and banged on the overrun, IMO the best aftermarket exhaust for the M3 and iirc tuv approved as well

I had Scorpion exhaust which was very load. Needed to get the car under the 98db at Goodwood so stuck a Supersprint middle section on and kept the Scorpion rear. Bang on 98.
Mark south of Dorking sorted out connecting the middle to the rear. I have not looked under to see how he did it as I thought...best not to.
All good fun..

Hi,
I can also recommend the supersprint system with the centre box.
I have the mormal twin tail pipes and not the DTM style. The DTM look isn't to my taste.
The sound is good. It sounds really good when you give it the beans and is fairly quiet when crusing. There is no boom or drone what so ever.
I've heared that the supersprint race system is very loud.
With regards to the cone filter into the standard AFM, this is something that I was looking to do myself but never got round to actually doing it.
There is a guy on the S14.net site who has done this and it looks quite good
His username is larsenracing if you want to serch for it.
He has posted pictures if the fitment and brackets etc.
Another option is to fit the Sport Evo air box to your car car, This gives more air flow to the engine and I think that it doesn't cost too much either.
The DTM howl is caused by induction resonance in the carbon fibre plenem.
Just fitting the cone filter to the AFM won't give this noise (apparently) so I never bothered.
If I were you, I'd log on the S14.net. There's so much info on the e30 m3's it's well worth logging on.
