PS: FE when stock was 14kmpl (city) and around 19kmpl (highway). Also note I had upsized tyres (205/50R15).
drifter- how much did it cost? and who did it for you?

If I remember correctly, it was around 7k and Automech from Mumbai did it for me.

Guys thanks for Automechs number. I am thinking of driving to Bombay one of these days and getting one fitted on my Fiesta, but I wonder what is more important. Should I fit Goodyear Eagles first or the good sounding silencer Can't do both at the same time....shortage if VitaminM

Btw, I didn't know diesels could also have nice performance exhausts

Zen Di being a non-turbo would not be doing too well with less low-end grunt. an FFE would surely help but do keep in mind that whatever headers and intermediate pipes you get, they should be just a little bigger than your stock pipes and headers and not a big difference.
Eg: If stock pipes are 1.5" iin diameter then it would be best if you went up to 1.75" pipes or max 2".
This will help you to free the exhaust and better scavanging from the cylinders and also maintain/gain a little low-end grunt.
Anything bigger will result in power loss.
The sound, apart from the end-muffler can be further regulated by a mid-muffler.

Word of Caution

For All people with TURBO-DIESELS cars.
When looking for an FFE it is best to keep away from changing the stock headers

MODS:Please delete this post.

When looking for an FFE it is best to keep away from changing the stock headers as it will affect the turbo settings. Unless the person you are dealing with is well versed with designing Turbo headers.

I think you haven't seen Isuzu engines in marine applications where they have free-flow mufflers.

Indirect Injection Diesel Engines
In an Indirect injection the fuel is sent to a precombustion chamber usually called prechamber where combustion begins and then spreads into the main combustion chamber usually cylinders, assisted by turbulence created in the pre chamber chamber. Therefore, this system allows for a smoother, quieter running engine, and because combustion is assisted by turbulence, lower injector pressures and high rpms.
These also require glow plugs to preheat the chamber in order to warm the air inside it in order to facilitate the starting. Usually a Rotary pump is used in Indirect injection engines because of its high efficiency and precise timing.

Direct Injection Diesel Engines
In Direct injection Engine the fuel is directly sent to combustion chamber through mechanically governed nozzles and the ignition is carried by high compression ratio inside the cylinder. In this way it uses no prechamber for pre combustion it solely relies on high compression ratio more than indirect injection engines. It also makes more noise and puts more smoke due to latency of mechanical governor pump. though some models use rotary pump which smoothens NVH levels.
These engines require back pressure cos the inside pressure of combustion chamber is very high, if directly mated with free flow mufflers these can lead to scavanging of liners [cylinder wall] due to cold air outside after completing exhaust stroke.

Common Rail Direct Injection
They are same as Direct Injection Engines but the the distributed pump feeding individual nozzle is replaced by a common rail single pump and the injector nozzles are controlled by computer to offer more precise and adequate timing in conjunction with rpm and throttle response.

Default Can Turbo diesel engine be "FFE'd" ?

We know the sound, err.. music that can be made out of a Petrol engine with a good FFE.

I've been told by several people that a FFE make no sense in a Turbo Diesel.
I don't know how good or bad it is (the music factor) in a Petrol engine.

So, now the million dollar question.

Can a turbo diesel be FFE'd ?
More importantly will it sound good ?

Turbo takes the energy out of the exhaust gasses (or so I've been told) and FFE in a turbo will not make matters any better ?

If this is true why we still see mufflers in turbo diesel cars ?

If any one has done it, please share the magic.
A Black Swift VDi is waiting to be FFE'd

Note to MOD's : Searched and found no thread exists for this, if thread exists kindly merge.

To be sold later to petrolheads :-)
I think you should be able to add a bigger dia exhaust pipe.
Can possible forget the sound improvement factor.

Just putting a big fat end can on a deisel will give you no roar compared to a petrol. IMHO it is a waste of money unless you wanna do it only for the looks part !!

The headers are best left as it is. You may run into unforeseen issues.



Cheers

Default Re: Sports exhaust for a diesel

Try Aero Exhaust from USA available to indians thru 20north.com, amazon.com or even ebay.com
costs 8-10k, lifetime gaurantee, stainless steel, and best of all, V8 like roar from the exhaust.
my mm540 has the same muffler, and i still beat modern cars in traffic light races, and the sound will make you addicted to rev more.
the specs are available in their website aeroexhaust.com and if you get hold of a good knowledgeable tinker, you can fabricate it locally for 3-5k.
Lastly aero mufflers are the best (IMHO) for diesels - better not to put it in petrols, as the bass sound will make you drive nuts. (pls avoid this muffler in petrol cars).
Cheers.
