320D Downpipe

So ive been wanting to a downpipe on my lCI 320D for quite some time now, just the current going price of R3000 + for one has kept me away untill now.

i Saw Powerflow Randburg was running a November special and decided to take the plunge. I woke Saturday morning and almost decided not to go as i started thinking "what if being a bmw it actually doesn't like the change, will it smoke to much, what if the workmanship is crappy and then its to late, i need shocks, maybe rather get Koni shocks instead etc etc"

Regardless i went ahead and went for it.

The workshop is a major improvement over the old one.
It is spotless and more waiting areas (as it is always a looooooooong process, left there with a hell of T shirt tan lol) arrived at 7:30 left at 12:00.
The customer service is very good and professional, they were very hospitable and called me to show me the downpipe once finished and once installed to inspect the fitment etc. Glad Sanjeev hasnt changed the level of work since i was last there 6 years ago for my Audi's downpipe.
I was stressing of shoddy workmanship or welding, due to mixed reviews on different forums. Sanjeev called me to check the finished downpipe and i was more than happy with the work. they used the original inlet part of the original cat to ensure a perfect, airtight fit. the welding was smooth, inside too.

Now for the downpipe:

Is worth it, hell yes! If you are skeptical as i was, dont be!

Sound
I wasn't expecting any sound difference at all, possibly just more the usual turbo whistle that is normal with tdi with downpipe. dam was i pleasantly surprised. After the installation the one owner takes the car around the parking lot to test for rattles etc. he floored it and wow! Its actually gruff. The nice guys i met there who were having there polo gti' and golf R done all looked at me and laughed because they were suprised at the sound. Under normal acceleration there is no difference in sound. Slightly more turbo noise but barely noticeable. only at about over 60% throttle from 1800 revs does a gruff, almost "braaa sound" sound emerge up till about 2500, then it just sounds completely different. I still cant get over the sound and cant wait to leave work to drive the car again. its so cool being excited to drive your ride again.

Drive/Engine Characteristic
It took about 100km of driving to really feel the adjustment in drive.
at 1800rpm there used to be a bit of a lag till 2100. That is now gone. Its smoother, and i actually need to check the top end. been loving the sound in the lower rev range to actually focus on the upper end of the rev range.
It definitely spools quicker and feels, lighter and smoother to rev. more natural if you will. It definitely feels like its making more power now. Im keen to dyno the car now to actually see if released a bit more torque or if it is just a mind thing.

Consumption
They disconnect your battery for the safety of the ecu, so my avergae was reset. after leaving the workshop my average was 12.0 lol. that was obviously checking how much more she smokes and trying to hear the sound and feel etc. I then had a family braai so jumped on the high and reset the average. by the time i got home it settled to 4.4L/100.
I need at at least 2 weeks to check the real life average. before it was always 8.0, so im keen to see if it will improve after the downpipe.

Smoke
Does it smoke more, yes. My car is mapped. normal driving not more smoke than normal. when you accelerate hard, there is now a constant trail of smoke. not sportline or cupra thick, but just a small trail. i kept my droopy tail piece so it helps that it points down. the back of my car is not covered with soot at all, so its not that bad.


As i was hoping to find no one actually has posted before and after dyno readings after downpipe, so im hoping to go to kar or h&m and doing a run to see what actual power difference does a downpipe make on our little 320D's



Before:

After

so next is dyno test, very interested to see what difference it makes in power.

Congrats bud, it looks great. That's an excellent write...so much so, that if I were contemplating a DP, I would be convinced.

Great stuff :smilebounce:

Glad you decided to have it done :bravo:

thanks so much for the advice bra!

i don't regret it a single a bit!
and i was wrong.... E90's do change their sound with down pipe only lol :roflol:

really impressed with our little 2.0D's :bravo:

yours with your weight, and that excellent gearbox must be such a mean drive :thumbs:

Awesome review there.... :praise:

now maybe i should do this to my one...:eek:mgwaiting:

I cant recommend it enough

Ive completely fallen in love with the car again.
more power, all the torque you need for safe acceleration for overtaking, and all with improved consumption... what else would one want!? :praise:

i definitely recommend taking advantage of any black Friday or Christmas specials on remaps and go for it. you will not regret it! :thumbs:

I had my 320d LCi downpipe done at Powerflow Randburg as well, about 3 1/2 years ago...my experience was exactly like yours...proper workmanship, hospitable and work done right, the first time around!

Enjoy it bud...it is so much fun and the sound is damn addictive!

NB. the sounds changes a bit whn you change the droppy tailpiece though...sounds more gruff with the droppy.

haha, im keeping droopy :roflol:
im keeping it so:

1 - the smoke blows downwards and keeps white tush white
and
2 - when i give a Polo Gti or Fiesta ST a chaia, i want them to see that droopy tail piece and know it was a 320D :smilebounce:

you must go and dyno Filv. What SW you running at this stage?

excellent write up.

I wanted to do this on mine since I bought it , but was reluctant, I recently fitted new tyres and taking it in for new control arms, if I still have it a year from now I will definitely get the DP fitted.

what map are you running?
is the money spent on a DP and software really worth it?

I am running ChipLogic software, with a mild map that was designed not to max out the gearbox and not smoke to much.

My Personal opinion, if you don't do this conversion, you are truly missing out on what the true potential of this Car is. It really does awaken the car up. it makes it more dynamic , sharper and smoother even. definitely improves owner satisfaction and driving pleasure.

I had map only for over a year. That completely changed the car. i used to not feel confident in overtaking maneuvers when it was stock as it felt like it ran out of puff after 3000rpm. That surge of torque was great, but short lived. After the map, the surge of torque greatly increases and you get that shove in your seat, as well as it feels as if the power keeps going right to the end of the rev range. I associate this with the flat power curve that most mapped 2.0D get at the end of the rev range, and you feel it. Consumption wise, my car after the map actually dropped by 0.2 L/100km.

I dint expect much difference with the downpipe, but it actually does.
It takes about 200km for the ecu to adapt and for you to really feel a difference. it eliminates that slight lag that was there between 1800 and 2000rpm. the engines feels more smoother and linear. As well as the sound. driving normally there is no difference to stock. when you plant it though, it actually sounds mean lol! Consumption wise after downpipe im still raking up enough mileage to say. i want to do at last 2 weeks of my normal commute and routes and then can say if any improvement. But judging o how it feels now, and how it seems to sit on lower consumption on my daily routes, im expecting my average to drop by another 0.1 ;/100km. time will tell

As for worth it... yes 200 times over! you end up with Golf 7 Gti power and frugality to get over 1000km on a tank long distance... what else would you want?

Hope this helps, :thumbs:

In shot yes it is really worth it!
