custom exhaust, dpf delete and remap for 335d

Today i have rang my preferred garage to have the work done,

Full exhaust system 3" then 2.5" where it splits 450+ vat
dpf delete pipe 200
in house remap but not dyno'd which bothers me a little bit 200

And they could fit my eibach springs for 35+ vat @3 hrs?

What do you guys think?

I have to go over leave my deposit and book it in.

VFM at those labour rates is excellent. Bang for buck will be unbeatable, sad yo say from a different perspective but the DPF thing with a delete pipe is the only questionable issue, watch VOSA very carefully as they are just about to roll out an all new on line system which aims to be more stringent with stronger enforcement criteria (we are getting various info now about the new set up) therefore MOT stations will have had a shot across their bows as we have regarding their activities re passing vehicles with an 'obvious' DPF modification.

He said he could put a dummy dpf in, if that's right? Never heard of that before?

The 'smart' way to overcome this issue is to completely remove the DPF have it cut open on the factory weld internals removed then re weld directly on the factory seam then re install. Therefore when viewed the OEM DPF visually is in place. If the tester sees the DPF in situ doesn't see any tampering to the side of the canister (we've seen them crudely opened up from the side and poorly welded thst are bloody obvious) then from a viewing perspective whst can they say! Diesels are tested for smoke so if this is 'controlled' and the DPF looks factory in appearence then there you go I guess.

Sounds expensive, and I don't know anyone who could do it?

A decent welder will be able to 'replicate' where the factory weld is seen it done before need to I dare say question the place who was going to to the job for you to see your options. If this dummy DPF is up to the task visually it may be your answer.

I'll have to ask them about it then to see if they can do it, do you still get the same power gains?

What garage have u gone to mate if you don't mind me asking.

Most places gut the dpf dont worry about it power gains should be the same as if you had a dpf delete pipe.

When i had my MOT back in Jan the garage said they couldn't see my DPF because of the undertray?

Will the new rules enable them to start removing stuff?

New rules I think you'll find(though rules from VOSA can/do change by bulletin communications to MOT Centres like us)will still have the same agenda re covers it'll be noted that covers are in situ, they'll be no rules to remove covers therefore remove them to the best of my knowledge otherwise it'll lengthen the test. But if you look from underneath you can with a careful eye see the DPF location.

I think most MOT stations will glance/move on re the test as its tight in and the test doesn't really give you a decent amount of time to dealve deeper but if as a tester(and it's the testers licence)you have a suspicion (maybe the smoke test will give you a clue)there's nothing stopping the tester ferreting around it it's a grey area IMO. But VOSA's rules are for sure shifting and are/will get more stingent.

no, they are not allowed the disassemble the car at all.

Thats the point this "advisory" gives the tester an option to be lenient, because you can clearly see the DPF/lack of with the under trays in place, but him putting it on the system that he cant see it absolves him of any offence.

Lol but i actually do have a DPF and he put an advisory about the undertray blocking it so he couldn't see.
