Has been answer by a ex-member, they don't all sound the same yes which i've explained in my posts, the stock ENGINE noise is not like other cars but shock has a lite dump air sound.

So car is going in for another oil change and coolant leak inspection before the paint fix.

Can i can what does the standard st sound like? i keep seeing them out now down my end and they look untouched but they get this loud flutter (from what is said on utube) and when changing gears like a dv going off (like induction sound)

(i've watched many utube videos but they seem mapped/modded and not much on real standard noise)

The standard car with standard exhaust doesn't actually make that much noise, although the resonator thing does increase the noise into the cabin.

I'm not entirely sure what or why you're asking 馃槀

on mine foot to floor let off between 2k and 3k and it flutters like the old escort Cosworth's 馃槅 anything above that then i just get the usual sound,, i believe as soon as you add a group a of some sort it will do it with the standard reciric valve also.

I'm asking as like i said in my first post, if its not meant to sound like a rattle can then one knows something is up with the car, its a simple question to see if the tone of a car is the right tone. :rolleyes:

@marco_ST Thanks but that is a Stage 3 not standard.

@kenny_st That is what i was hoping for, loved my cossy and sound but i'm not getting anything like that (standard airbox)

you will get a low form of chatter but i was always told on these cars its not a good thing, i remember when people were fitting the 50/50 valves the back lash people were getting, I'm not sure if things have moved on since i was away from these cars for over 5 years, like when people started moaning about the group a filter it was a straight no no 馃し鈥嶁檪锔. i only get the chatter like i said above and is quite load, anything over 3k i just get the normal ptssss dump

I read about the chatter thing as far back as 06, very strange as these was untouched cars and still did it (factory defect?) I keep reading about the recir valve not dumping gives no sound other than turbo spool and can cause head problems! (not sure that is right)
I don't go over 3k but when i did to just try high rpm for boost (which i never got) it sounded like i was high rpm in 1st gear so i change at 2500-3k now but never get the dump sound i've heard on other "standard!" st's

The group A filter i keep being told its just a hot air filter and i was told this since owning my cossy,metro gti,xr2 & mgzr as they all had one.

If you are not going over 3K revs then I am not surprised you are not getting any sound as the engine is barely working or doing anything at those low revs! Keeping a turbo engine that low and pulling through the gears will not be doing it much good apart from anything else. The 2.5 has enough torque to do it but it is not ideal. Why are you only keeping to less than 3K revs because at those revs the turbo is only just getting into it's stride? As stated the standard car is actually very quiet as most turbocharged cars are in normal trim as the turbo keeps the exhaust quiet. If you are wanting more induction noise or turbo DV noise then you need to modify it - and rev it!
Group A cones can work well on some cars & are a waste of time on others. There seems to be no common factor to them which is why most people go RS airbox or CAIS. Then open up the downpipe & exhaust to at least 3 inch. Then remap to get the car working properly. At this point you can fit a DV for the sound but again some cars run them - other don't.
My old ST500 was very quiet in normal trim. By the time I sold her she spat flames, popped & banged like a machine gun, chattered & whooshed on gear changes (and spat more flames), and howled like a banshee on full chat. All down to the work I did on her. With the age of these cars you will either find cossetted - and valuable - standard cars (that are quiet & 'normal') or modified ones that make a racket.
So in short you want any form of after market noise you need to fit the necessary after market part - oh and rev the car.......................;)

I was told boost kicks in at 2500-3k rpm in 3rd this is why i kept to that, anything higher and i'm just wasting the boost.

I have a 3" and when its warmed up its a nice sound but still want the oem exhaust. I ask as i see standard ones and they sound completely differ than mine and when pumaspeed red lined my car it was over half on boost and staying strong but no sound was there.

Do yourself (and the car) a really big favour,find a long dry wide road,get into 3rd and pin the throttle,and keep it pinned, then near the redline shift to 4th and pin it again. Keep an eye on your speed in 4th though :censored:
I doubt if you will notice what the boost will be doing, but keep the throttle flat to the floor, You will see what your car is capable of if want it too.
If your only going to drive it up to 3000rpm then your missing out on most of the fun in owning an st. You don't have to drive like a loon to appreciate them but a little spanking does them good occasionally .:D(y):D

I can't remember the exact revs especially for standard but I thought the second kick was about 3k rpm.

If you're going to change up just as the car gets into its power band you're never going to be using it's performance

I always thought the standard exhaust sounded nice, just can barely hear it. You won't be able to compare the tone of an exhaust like that.

A friend heard my car going down the road and knew it was mine because she sounds different to any other st he's heard. His st sounded nice but was completely different to mine. Another friends car sounds amazing but completely different again, and you can't even hear mine start up whilst his is idling.

Fit a different pipe that is bent slightly different to another brand, or compare a new one to one that's been sooted up a bit, they all have slight differences.

And recording them makes them sounds different again most the time.

If your car sounds like a rattle can it's probably needing repairs and well past a service. If it sounds smooth, you can't really compare the tone, especially with standard which again is just quiet. They purr

I've Been told to boot it many times and i have done many times, the problem is the conflicting information i find on how to drive a high torque car like this (cossy was ages ago) so in the time frame i've not had the cossy to the st and the cars i've had that are low torque cars, Its getting used to the shifting again without f'ing the car up like most do.

I was told to red line it from the kid from pumaspeed, which he did to show boost but once i got back in the car and started it up the car shuck its t*ts off and rattled, I got told keep gear change to 2500-3k rpm as this is when boost kicks in, I've read going to 5k rpm before changing gear which i've done twice on a 60 road and the car moved great and sounded better after but 1/4 on boost gauge.

I've done it again after school run hitting 5k rmp before changing and boost went up but only just over 1/4 on gauge, I did not want to do it but had to pick some stuff up and coolant leak was fine so i gave it a try (don't drive it due to coolant leak and another oil change due)

A orange st mk2 pfl passed the house and i know 100% its standard and untouched as his been at the classic car show i went to last year and had a talk with the chap and his still has a air dump sound.

My son can hear my car two streets before i get to his college lol so i can agree with the exhaust tones part.

I've read through your posts and I honestly think your overthinking on how to drive your st.
I think your accelerating with not a lot of throttle up to 3000rpm with probably very little boost,maybe sometimes you rev a little higher but still with nothing like full throttle/ wot,hence lacking boost and it drives like a naturally aspirated car.
My advice find a local to you member,get him to drive your car and see what he thinks.
When my st was fully standard it made no particular noise that I recall.
Which cossie did you have to compare the st too.

For a standard car, torque reduces after about 4K rpm so taking it to the red line adds nothing to performance.
Thank you for stating this, I don't see the use for red lining to be honest with you and i know it causes more damage, this is why i kept it at 2500-3k on gear change, if i am on a the 60 road (not any more as i don't got to the care home now) i long shifted so i've hit the 4k before change.

1991 ford sierra rs cosworth sapphire, like a light blue one, got robbed by my brother who ditched it after a police chase :( glad nothing came back to me other than i had to say it got robbed.

I have read to never plant your foot down, you build it up till your foot hits the floor as it can wreck the crankshaft, I've tried to not be gentle on the driving, i did get a dumping sound when i first had the car and boost was never there which made me change my driving habbit to a more aggressive type (not a nasty driver but not a 1.4 driver still) things changed when i had work done to it, no dumping sound, lack of power, very low tone from exhaust, not the same st noise one hears from other st's the same standards. This is why i asked about the tone/sound its meant to make (non exhaust tone).

I never said redlining all the time, now and again does no harm at all.
I honestly don't think anything is wrong with your car, just chill and enjoy it.
Pumaspeed bud, not you . I said it above what the kid who redlined my car said.

I enjoy the car for sure, sons love it, daughter wants the MG back.

When I bought my car it had standard recirc with Group A filter. It produced quite a bit of induction noise but only very rarely did I hear any turbo flutter. I put on a Turbosmart recirc which made a lot more chatter, then switched the Group A for an RS airbox which made things civil again.
