Has anyone fitted an Eisenmann Performance Race Exhaust on a 325d?

I am very interested in doing so myself, but i want to hear exactly what its gonna sound like before i go ahead.

I can find videos and discussions based on the 330d & 335d which is helpful to a certain degree, but to bite the bullet and order i need to hear how this Exhaust sounds on a 325d.

Any help is appreciated, and if anyone has vids of other performance exhausts on a 325d, I would like to hear what they sound like, as this may give me an idea of how the Eisenmann will sound, problem is, alot of people have other extra mods that make the car sound better, so its very hard for me to find a true reflection of how my car will sound with this Exhaust alone.

surely the 330 and 325 is identical?

They share a stock exhaust system, so if you've found fitting info for the 330 then it will apply just the same to yours!

Been waiting to use this little guy
I want to hear what the exhaust sounds like, not find instructions on how its fitted, my bodyshop will do that...

the 325d and 330d are not identical in terms of sound, the engines are tuned differently, the 330d is more powerful - meaning it will naturally sound better with an aftermarket exhaust than the 325d would. I need to hear how the Eisenmann Performance Race Exhaust sounds on a 325d (as per whats written in the OP).

My bodyshop deal with Eisenmann all the time and know how to fit their exhausts, so that will be their problem not mine

My first response was not regarding fitment, it was agreeing with "surely the 330 and 325 is identical"

It's the same M57 3.0d engine, but the 330 runs more boost than the 325, so there will be very little difference (if any) in the exhaust noise between the 2 cars.

Therefore in the absence of 325d exhaust videos, you can only use the 330d as a basis.

Ahh I see, in that case you've proved very helpful haha, thank you very much and will update when I purchase with the first vid of a 325d with this exhaust

Hi, got another spanner in the works!! I just called Eisenmann directly and the guy I spoke to said that fitting the race performance exhaust to my 325D will make no difference to the sound whatsoever, surely this is incorrect guys??

[Aragorn30d]

I would imagine that to be largely true, especially if the DPF and Cat are still installed.

Maybe a little extra grumble from outside but probably not much.

Ahh thanks, that's so disappointing though bro! I didn't know any of this sound related difference stuff when i bought the D car, wish i went for the petrol now!

[Aragorn30d]

For instance heres a clip on youtube of a completely straight piped 330d, that still has the DPF and cat fitted:

Not the best as its in a reflecty car park, but you can hear its not that loud.

If you go into the guys videos, there are some of the same car with the DPF deleted and you can hear the difference.

[Thermobaric]

Doesn't the 330 have a valve on the exhaust that the 325 doesn't have?

[Aragorn30d]

nope, not on the diesel.

Thanks mate! I'm thinking of getting a DPF delete (one that will still pass an MOT), my question is, does deleting the DPF have any negative effects on the cars performance or cause any long term maintenance/engine problems? From what I've read it seems one day I'm going to have to either get a new DPF or delete it anyway..

Anyway, I'm not looking for my 325d to sound like a jet, just want it to sound a little mean and aggressive

So you want it to sound my like RS focus mk2 did

[Rich_D]

If you have the DPF removed by carefully cutting open, hollowing out & welding closed, if it is done properly (like mine) you can't tell once it's back on the car and it will pass an MOT.

However it will need to be mapped out and you'll get more power & torque at the same time, it's well worth doing, trust me!

In my opinion this is a big waste of money - the diesel will just never sound good. I looked at all the options for making my 335d sound good and in the end bought a cheap second petrol straight six car for the weekend. I've heard everything from boxes deleted to full DPF delete, and - again just my opinion - the only mod that makes any significant difference is the DPF delete, but the resulting sound is a love/hate thing. Personally while I don't dislike the DPF removed sound, it doesn't come close to the awesomeness of a good old petrol engine and therefore would leave me dissatisfied.

I'm not criticising your decision to buy an exhaust for your diesel, please don't take this the wrong way. I have just explored many different directions to improve the sound of my 335d and found none of the to be adequate for my requirements and all of them were very poor value for money, i.e. big cash, small improvement.

Also worth noting re DPF delete: not only is it an MOT fail if they spot it, but they may well get stricter with the tests following the VAG fun and games.

The video is a Focus RS, it's clearly not a diesel, it's a 5 pot petrol engine with a turbo!

The plan would be to do it as you have mentioned yeah.

When you talking about the re-map for performance is torque, is that done because removing the DPF decreases performance?

I know you obviously have to get the map that stops the ECU from showing error codes and DPF light etc. - but is the performance and torque map needed? Or just an extra that people do seeing as they are already getting the car mapped? Been confused about this for a while!

If you're not sure, could someone else please Clarfiy the above question please!!

I wouldn't want to increase power and torque at this point as I want the car to last as long as possible and not mess with too much stuff, I'm just doing this for the extra powersound and a couple horses.

lol sorry I have no idea about ford focuses!

Lol no worries bud,have you ever thought about selling your diesel and buying a 325i,because in my opinion too,no matter what you spend on your diesel it'll never sound as good as a petrol

[Aragorn30d]

MSportFury: You probably could get the DPF delete part of the map done, without the "tuning" part, but thats kinda pointless, and a remap transforms how these cars drive so its kinda silly not to just do both. A mild stage1 map will take the car upto about level with a stock 330d, and wont in any way stress any of the engine components, becuase they're all the same as the 330d anyway.
