Exhaust Upgrades

If you had a Z4 then any sound would be better than no sound that even the 3.0 have. I missed the little drone and burble of our old 3.0 Z3 that i had a scorpion exhaust fitted. Now our Z4 sounds just like our Z3 did
Doesn't it have that resonator/sound amplifier system from the intake through the cabin...? For some reasons I just assumed the Z4 sounded better than the Z3. (only recently the exhaust note studies have seriously developed)
 
The problem with fitting an aftermarket exhaust to our 6 cylinders IMO is that it takes really little to make it sound like..."cheap" (I am not sure this is the right word, but it's the one that gets closer to how I perceive it)
A V6 or a V8 can better benefit from a richer sound and still sound like "big" engines...whereas with the wrong pipe the L6 can get very close to a 4 cylinder...

Here is a 2.0 with stock muffler

Here the same engine with an aftermarket
You must have some weird exhausts makers Belgium that can make a BMW 6 sound like a 4!
Even with a straight pipe there's no mistaking them. If you thinking about a system but not sure get to a meet and hear some actual cars, video makes it hard to capture and of course it sounds different when you inside which is what's most important.
 
For info, this is a pic of the tips of the magnaflow. Hopefully I get time to fit it soon, I really hope it sounds as good as it looks! Just out the box and initially very impressed with build quality.

That back box is tiny, will be loud for sure but after a straight pipe it's all relative I guess!
Nice tips
 
The stock 2.8 exhaust has a nice sound to it what frustrated me was asthetics in that the tail pipes where so lost in the cut out and pointed down .
I ended up with a 2 box system as wasn't looking for loud i wanted it to look right.
Any aftermarket exhaust / sports system is going to be louder but i achieved a nice balance and love it :thumbsup:
 
Worth remembering that a given exhaust is carefully designed to work with a given engine. It's very easy to, say, get more noise and lose performance. Look at the "dustbin exhaust boys" - my wile calls them "little willy men" which is likely quite rude!:)

I do understand what you are saying, and I have never had a custom exhaust before partly for this reason.
But as I bought the car with straight pipes, as the PO thought it wasn't very 'punchy' stock.
I really does depend on each individual opinion, but I feel a beefier exhaust really adds to the character of what I want my z3 to be.
It makes the car feel more exciting for me, and a different league to fartboxes

If it does it does not work =))
 
Ps if your car is going to be down in Kent for work then speak with @Tim beard (In Bexley) - he's had an awesome dual outlet system made for his Cobra Z3. Sounds very different, much more muscle car than others I've heard.
Actually it's likely going down to Martyn Scott's in Dartford shortly so will drop him a line.
 
My 99 2.8 has had a full cat back system .i paid £290 with custom pipes in Doncaster.
Having added a full Simota induction kit too i had a stage 1 remap and have been very happy with it.
Its certainly changed the car.
How much! Was that like donkey years ago :o)
 
I'm selling straight pipes for a 2.8, in the for sale section, there's links to videos of me driving with it.
It's very loud so I've got a magnaflow to replace it, but I am 5050 as I don't want it too quiet, it really does sound great and poppy on down revs
Think I'm a bit too old for very loud lol!
 
It wasn't that long a go just over 12 months now was a good price that was quoted and have been very happy with it :thumbsup:
I can vouch for the sound from fetching it the other week Ant.

Tony.
 
Custom chrome Nuneaton are brilliant they will design and hand make ,your system specify to what u want, they made mine last year which a lot people say it's sounds amazing, I've got a lazy cat on mine , and I'm planning to get them to fit sport cats on it which they make, and it's sure to be a bit more free flowing hopefully.
 
Well that's given me food for thought! I might be doing you a message @Antm72

How does the Magnaflow sound then? What Month/Year is your 2.8 - I saw the Magnaflow on eBay but think it was for the pre-TU engine.
 
MIJ performance in Birmingham fitted a cat back exhaust to my Z3 for £295 a couple of months ago.

They also do a quad setup including cutting the bumper for £360 if I remember correctly.

Looks and sounds awesome. Also comes with a lifetime warranty so long as you own the car.

Here's what it sounds like

Hi all
I have recently bought a 1.9 2002 Z3. I need to change the back box which is blowing. Can anyone recommend a back box that can improve the sound to something a little more performance wise. Or should I have bought a 3 litrethanks. Simon
