Its naughty from a warranty and MOT point of view really as its part of the emmisions system. But with the correct size exhaust it does allow better exhaust flow.

Thanks Pete.
The two snippets in your videos do sound great. 
Will tap the brains of the local MOT testers here in France to see what would happen if I removed the DPF and chopped out the silencer. I see some real trash driving round here and wonder how they could ever pass the CT (MOT), so live in hope that a small emissions change might not be high on their radar.

If you do remove the DPF do remember you will need a non DPF calibration putting on the engine ecu to match or you will have mil lights on. also make sure if you remove the dpf contents from the "Can" replace the contents with an internal pipe as not to have the gass flowing arround an empty space.
Then leave the centre and rear of the exhaust as is for now or you could end up to loud. Pete |

Thanks Pete. With that in mind, if I am after just more free-flow and rumble, would it be easier, more cost effective and less risk with MOT just to cut out the middle silencer and go for a simple straight through SS upgrade? Leave the DPF as is? Monsieur Le Grenadier

Removing the centre and even rear boxes on a 2.2 does nearly nothing at all,,, if anything a very very slight deeper note but not worth the expence of anything stainless or explencive for sure.. the DPF simple kills all noise.

Gotcha.
Brilliant info Pete, thank you. May be in Yorkshire for work in a couple of weeks time, so could swing by and say hello and see what the Tuning is all about, if OK with you? Monsieur Le Grenadier I've not been everywhere, but it's on my list..... 2011 Puma 110DC - Corris Grey |

What about removing the centre exhaust on a 2.4 (one with a BAS v2 map)? --

No problem Grenadier
. Naks, the 2.4 is different and does alllow a little noise from the exhaust even with its CAT still on the front as it does not block the sound as much. Do only keep to the same pipe diamiter as standard though. Large bore stainless steel shiny expencive looking exhausts on this application are a waste of money, and most are just put together to look good with no real testing on back pressures and flow etc etc Ive not seen yet anyone who sells exhausts meassure temp and back pressure after the turbo, they just sell shiny parts hehe. They may be should make something like this as I did to take some measurements  This bolts in the exhaust after the turbo and before the front pipe.

Thanks Pete.
As an update, I noticed your other thread re the DPF (must give you nightmares... ) and for your info, should anyone approach you about DPFs upgrades for French vehicles, whilst it may invalidate the LR warranty full removal (or adjustment) does NOT fail the French MOT (Control Technique) as the French test is purely for fume 'opacity' not for particulate levels. (And judging by some of the  churning out of 40 year old Peugeot Dianes, the opacity test cannot be too stringent  ). Monsieur Le Grenadier

DPF do give me nightmares legally yes. Good news on the French laws than you, its handy to know do they make a visual check for a DPF when the car goes for Control Technique or only Opacity ?. How would the certificate of conformitybe effected for the car in France or is this only used for first registration and or importing cars ? My knowlage of the details in France is limited hence the question. Regards Pete |

Apparently not. There might (as per the UK) be some kind of 'modifying of cars' regs (According to 'Honest John' the DPF falls under the following in the UK: Regulation 61A of the Road Vehicles (Construction and Use) Regulations 1986), but as far as I can ascertain this is not the case in France or looking at it another way, it may not be technically legal, but it WILL pass the CT. I know if they want to that Gendarmes, like the UK Five-0, can do more thorough inspections of cars when desired, but as far as the national test is concerned, emitted particulate matter is of no concern.
I hasten to add that this is Google research via forums, a couple of CT centres (advice pages) and some French Tuning centres who advertise that the car will pass the 'CT' albeit they are not clear as to whether it is strictly 'legal'. Further, there is no saying the French won't change the CT. However, given it is a bi-annual test and given the state of some rurally-based vehicles, (not to mention their owners ) and the size of the country/difficulty following this up, I cannot believe the French state would bother. They are happy to force through EU laws that the UK kowtow to without necessarily giving a tinker's cuss within their own boarders. Given the number of diesel drivers, the lack of public transport in rural areas, the clout of the car-giants etc, I cannot see much happening to the detriment of the average diesel driving Frenchman.
Now that 'lunch' is over and the CT centre open again, I might pop down and see what they actually say.... Monsieur Le Grenadier

As far as I am led to believe, the EU Certificate of Conformity is a one-off to get the car registered. I completed my wife's Mini just last month and the Prefecture kept the CoC plus associated docs, they did not copy and return the original to me. I have no idea whether it will be returned at a later date, however the car now has the Carte Grise (V5), plates, insurance and CT, so is tickety-boo. As such, I assume the CoC is a one-off. For that, you can be sure they will make the test, as it is done by a registered Garage (i.e. Main dealership) of the brand of your car. So I am sure they would look at the DPF too. But after that? I am passing my local CT centre shortly, so will ask about the visual check.....having said that, I have heard there is a huge discrepancy between CT centre standards locally and nationally. For example my wife's Mini has run flats which should technically be present (actually on the vehicle I think) at the time of the inspection. Not only were my wife's tyres stuck in our barn 20kms from the centre, but she also did not have the original wheels, but steel 'winter' wheels with snow tyres. The car sailed through....And the number of Defenders I have seen here with full steel A-Bar rigs (plus lights, winches etc) that would be illegal in the UK and they have no problem. Indeed the local Defender independent, when asking about EU LED lights, said 'we just stick on what we want and get on with it...'. Maybe he knows the local Police commissioner? Will let you know re visual inspection... Monsieur Le Grenadier I've not been everywhere, but it's on my list..... 2011 Puma 110DC - Corris Grey |
