Whats the concensus on the above ?
Is it difficult to fit ? I changed the one on my S3 8L, it took me 3 weekends to get right, a right bitch to get out involving reciprocating saws, dropping of subframe and propshaft. Was worth it though, spool up and torque so much better. Also Brucie bonus of better mpg and lower egts.
Car is FWD ... so no prop this time.
-
If you have lift it will be very easy to fit... :)
-
I did it with the car on 4 jack stands, but it was a horrible job. Wore out 7 blades cutting through the flexi pipe and DP. I had to destroy it. From what I can see, the mk5 *should* be easier, if I can get the nuts off the turbo outlet flange without it seizing or snapping the studs. I'll spray lots of plus gas on it first. I'd hate to start the job and find I snap one or more of the studs ...
Dejan, I see you have replaced the baffled turbo outlet with one without the silencer. Was it difficult to remove and fit ? It fits between the turbo and the DP ?
-
Just take it to a garage or rent a ramp. Done in an hour or two. And a much better fit
-
Well I bought the thing B.I.N. and not the auction. Let's see if it's any good.

In one hour you can have change it if all fit perfect without modifications. Afcourse if you have lift/ramp on jack stand it is very dificult but not imposible you will only yspend much time...
turbo outlet is on cold side(pipe connected to intercooler) of turbo not on hot side(downpipe)... When I had turbo down on desk it was very easy to fit(3 bolts) with turbo on car you must remove pipes/hoses and then you can change it...
-
I see. The silencer is on the cold side.
Do you advise getting new turbo flange nuts ? Turbo hot side gasket ?
Probably need a new clamp.
I think i'll get a quote for the work in a garage, as it is starting to get cold now.

I've just taken my decat off and fitted my standard cat . Did it on the drive in about 1h 30 mins quite easy if you can get the car hig enough I reversed onto my ramps and jacked the front as high as I could and put the front on stands , it's fairly straightforward from there :happy2:
-
Are there good places to jack the car up on ? I have a trolly jack and 4 stands, but I want to avoid chewing up the underside with the jack.
-
I just use the jacking points on the sill , there are arrows on the sill where there are :happy2:
-
it's arrived :pomppomp:
Looks very well made.
-
Ive also got my eye on the above ^^
Good to hear its well made! Is this going to be mated to the stock cat back system?

There you go. Unboxing 2.0 tfsi 3" DP and sports cat
Observations
Well packed
Good quality stainless steel
Welds look good and strong
Threads look good
Cat is a metal matrix type and not ceramic
No pre-cat
I measured it as 74mm, tapering to 60mm to connect up to stock system. This bit will be cut off if you have a 3" cat back system to maintain the same pipe size.
Here is a Milltek decat pipe for comparison.

Good to hear its well made! Is this going to be mated to the stock cat back system?
Yes, I intend using the stock cat back. Need to save my pennies .... for a HPFP :evilgrin:
-
Looks very promising! :happy2:
Are you getting this fitted soon? Will be interesting to hear your feedback once its all fitted and mated to the stock cat-back system and how it sounds/performs.
HPFP will give you some big smiles :evilgrin:
-
:party: :popcornsoda:
-
Very interested to see what you think of this little mod? Was only looking at this the other day? Feel any different under acceleration or sound??

I want to get the engine pendulum mount (large & small) sorted out first, to minimise the chance of the DP cracking. This will have to wait, as there are loads of other things vying for my cash .... Ideally I'll have a fmic, hpfp too, which will probably mean the demise of the clutch, so a Helix FP and DMF will be needed too.
But before all that, I'll also do some baseline logging of EGTs and lambda to make sure the car isn't running too lean with the new pipe.
-
I've just bought the cheap sports cat off eBay. They always do second chance offers so I never bid over £150/160. I've done this a few times. I'll be getting it fitted next week.
-
What will this do if I fitted this to my stock system?
-
I think this is the same dp I have been running for a couple of years. I have mot'ted it twice and it passed emissions both times. But it was close, I did heat it up very well before to make sure it passes.
Installation is very simple. You might want to soak up the turbo nuts before installation. I had no problems with them and applied copper grease etc when installing. There was a bit tension with the mount to the frame but it has held up well. Its mated to my stock catback and really opens up the engine. Good increase in power and fuel consumption goes down.
For the money I think this is by far the best mod for my k03 mkv GTI.

re MOT that's the experience I've had with a similar cat & DP for my S3 8L, the bonus being it spooled up a lot quicker and the mpg improved by 2-4 mpg.
The one for my mk5 is waiting for me to put it on...
-
Got my sports cat fitted the other day. Seems well made and fits good. But I literally drove it 15 minutes to the garage to get the wings replaced so not had chance to let it bed in yet. Mates upto my standard cat back no problems. Until I get my BCS ordered to really liven things up.
It certainly felt different to drive. And sounds a bit fruitier.
-
Did you fit it yourself ? Did you have difficulty with accessing the nuts ? Any gotchas ? Any tips ? How much of the car did you have to dismantle ? Does the subframe need to be dropped etc ?
-
I fitted my DP on axle stands on my drive. It was doable, but not a lot of fun! Trying to reach the flange studs and be able to put enough force into them, while lying on your back!
I put PlusGas on anything I could reach, didn't drop the subframe or anything like that. Unplugged a couple of sensors, removed a bit of beat shield. Followed a guide I found online (might have been Briskoda?)
-
just get a garage to do it. nice and easy on ramps and they do a better job if you know someone decent.
i removed most of my ITG cold air intake to give better access. topside of the engine bay then we put a long reach extension bar down the side of the block to crack off the nut that's hardest to get at. the other 3 are easy from underneath. you need to disconnect both lambda sensors as well which involves removing plastic guards underneath etc.
-
Thanks for the feedback guys. I've done it before on a S3, but it was a horrible job, involving a reciprocal saw, many blades and disconnecting the propshaft and dropping the subframe. Later I found I couldn't do up the dog bone mount as I moved the engine so much it wouldn't line up. Ended up having to loosen 3 engine mounts and starting the car to get it to re-centre ! :fighting: Did all this on my driveway. Car was off the road for two weeks.
I vowed never to touch one again, till next time :rolleye:
I'm trying to gauge how difficult a job it is and whether to pay someone else to do it.
How long did it take ?
-
It took me and my mate about 1hr 30. We didn't rush it just took our time and do it properly first time.
Sounds like you should know from past experience to get it on some
Proper ramps. I'm all for DIY but it's freezing and I CBA :happy2:
-
Ive got one of these for fitting, but haven't even weighed the job up yet... Is there any other hardware required(clamps/gaskets etc) for fitting to a 2005 gti(axx)?
-
I got around to fitting mine yesterday, the quality is great and generally the fit is good, but I'd say the overall length is maybe an inch to short for my liking. Because the exhaust is clamped to the std rear section by means of a slip joint, the two sections want to pull apart - I have secured the joint with 67mm exhaust u-clamps, that grip hold of both sides whilst clamping the joint too. No leaks. I had to cut off the original clamps anyway, as they were rusted quite bad, and ceased.
Anyway, the downpipe has made quite a difference to how the car picks up and how it holds more power through the revs, well worth it for the cost :-)
-
Ye I thought that about the length. But I justed used the original clamp with new bolts and was fine.
-
hi, have recently just fitted one of these,
had it running a week on my edition 30 and no eml yet.
i have however got a 42 draft designs O2 spacer.
sounds a lot better when driving hard but still relatively subtle when driving daily buy i have still got the standard
rear section.
seriously impressed with the quality for the money, can't go wrong buying one of these to be honest !
-
This is very tempting, I already run R-Tech stage 1 - could there be a risk of reducing the maps performance by adding this downpipe and not redoing the map?
-
Really tempted to buy one of these as seems a well worthwhile mod, does it make the sound a lot noisier inside/outside or is it still close to stock as I don't want something that sounds like a boy racer.
-
One on eBay at the minute
http://pages.ebay.com/link/?nav=item.view&alt=web&id=351339060433
Could be a bargain!
-
Had mine on a few months now still fine. And passed mot the other day well under the emissions levels.
