Does it proper roar louder than the Bosal :-) ?
How long does it take for baffles to go :-) ?
Not as long as it would take barry to cut open your new full scorpion stainless steel brand new fitted full exhaust system boxes and remove them :wink: winkeye

The value of the exhaust would reduce with that
I think better to let it go naturally

Feels more powerful for sure
Between 5-6k rpm I can feel the power tail off

Do people understand what baffles actually are? :mad:

On a scorpion exhaust I would be amazed if the centre box is anything other than a twin straight through reso that has is made up of two straight bits of 409 perf surrounded by E Glass. If it does have a supporting baffle, then the chances of that giving up are slim.

When the E glass "balls up" because of excessive heat and a lack of stainless wadding around the perf, then it might howl as there is no E glass to dampen the noise.

It might not even have a baffle in it! :o

My Scorpion, albeit from a M3 has a separate resonator which is pretty much a hollow silencer,like so...

Image


Not sure how true it is but i heard on standard E30 scorpions (like Pony's) the front half of the centre box is hollow and the rear wadded?

Suppose you could test this by tapping the centre box with a screwdriver, if it pings half way down my theory is true.
If its a dull thud all down im chatting shit. :)

Whatever is inside the centre box of a 325i scorpion system, it doesn't last and the box ends up sounding very hollow.

How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

You know exactly what you are doing, all I am saying is it is proper childish and boring for a fully grown family man to be doing, but it is your call.

EDIT, just seen your edit, sorry OP! (I am not starting a thread Rav)

Just been for another drive in the Sport

Really starting to roar and reverb under bridges
Though not quite as loud as I would like
Nice and subtle at idle and low revs

The engine actually feels smoother and like a Classic BMW I6. Feels more pokey. I think had helped.

Bss325i .... Bring your Sport to Surrey meet
I'll take u on drag race
No joke
Tech1 v Tech2
Lightweight v Fully loaded
Sport v Sport
E registration v G registration
170k mileage v 70k mileage
I'm ready
I got that Sport swagger innit :-)

Oh shut up Pony!! On some threads you've actually started to sound like a normal, reasonable person but then you go and let yourself down again with "want more volume- asbo loud" bolloxs. FFS stop being a sad attention whore and enjoy driving the thing without checking yourself out in shop windows and trying to scare old people with a stupid exhaust note- it ain't big, clever or kool!! You'd look far less a twat by not trying so hard!

No offence meant fella, just a friendly opinion for your own sake. You've started sounding 'normalish' lately, don't ruin it :thumb:

I had a Chiswick mum give me an "evil look" when I red lined it
They were crossing road but not on my side is road

Then she was waving hands to say what am I doing

Then I said

"Sweetheart this is E30 325i Sport which has the classic BMW NA I6 and LSD and New Scorpion Full Sports Exhaust System. If you had this you would be doing the same thing. Don't get jealous babe ;-)"

Then I left her to enjoy the aural pleasure of a Sport being given the beans
No doubt she masturbated over that sound at home !!

Sport swagger innit :-)

I did have a neighbour look at the Sport a bit funny while was parked up
He had Aston Martin DB7 V12 in a lock up no idea whether he sold it or not
He has Jaguar S Type and Lexus 4x4. He used to have E38 7 Series.
