Exhaust Sound Poll
So who's changed their exhaust sound..? I fancy a bit more character, but don't want the car to sound like a Subaru (or worse a Corsa) with a Chav booming exhaust.
What'e everyone else done?

Tricky one to vote on. Results seem to vary a lot based on model.

I’ve recently bought a 3.0si with a backbox delete and totally love the sound of it. It’s not actually too droney, a lot louder obviously...but the sound Changing up gears on the redline is utter ear porn. It cracks and burbles constantly every time I let off the throttle in all gears.
Here’s a little vid, it really doesn’t do it justice.

I have an Arqray backbox. I was hoping/expecting it to be louder than it is, but it’s a nice deep sound at low revs and comes alive at WOT.
It’s just a shame it’s not a bit louder, as my noise generator (both foam pieces removed) drowns it out

I've got a backbox delete with baffled tips on my 3.0si, to be honest it's way too loud at lower rpm for my liking. Sounds great at 4k+ and downshifts etc but everyday driving it's too loud and droney for me. Currently looking at other options.

I've got Mike's Zedshed modified back box on my e86 and, for me, it's the perfect balance of gurgles and tone that it should have come with as stock

I voted for full system, but luckily the custom cat-back system on mine was paid for by a previous owner!
Definitely sounds better than the stock system on my previous Coupe.

I put a Supersprint Race axle-back system on my Coupe.
However didn’t want to pay £1,800 for just a Supersprint backbox on my M3, and so I debaffled it and then welded in Supersprint esque pipework.
Either way, BMW’s systems just aren’t good enough!

I removed the backbox on my previous 2.5si and loved it. However, I modified the backbox on my current 3.0si and it is about half way between stock and full delete but doesn’t pop on lift off. Both have been weekend cars so I’m not bothered if they are too loud.

Eisenmann race on mine. Definitely tuned noise rather than just louder. Quiet down the Rev range but opens up past 3k and sounds lovely and metallic past that point. Lots of crackles and pops but not as loud (gunshot like!) as a backbox delete.

That is interesting. Once warm, my si (also a 2.5) used to pop and burble away quietly all the time on lift-off. You’d assume that would translate into lots of nice noises with a modded backbox and that the 3.0si would be the same.Doddsy wrote: ↑Thu Mar 14, 2019 12:05 am I removed the backbox on my previous 2.5si and loved it.

The ///M doesn’t make anywhere the same amount of lift-off noise. I would love an aftermarket exhaust for it, but a lot of them are a bit “parpey”, which makes them sound like a chav’d up Corsa next to something like a Boxster with PSE.
Goes back to my point above an “all models” poll being difficult to get anything from.

Did this on the way to work this morning, gives you an idea, this is roof/windows up 3rd gear across the full rev range, doesn’t pick up the volume well either.

Only got my Z4 last week but it's got an aftermarket exhaust on it (Powerflow). Mixed feelings as it does drone a bit on the motorway and sometimes would be nice to be a bit more discreet but the pops and bangs appeal to my inner child and the noise going through a tunnel the other day was pretty amazing! On the whole it adds to the fun of the car and I like it.
