Wonder how it flows compared to the original Milltek DPF delete pipe

Eh?
So they've welded on a little box to make it seem like there's a DPF? Or is this a "sports-DPF"?

I'm guessing from the looks of it, it's the former. But it looks quite different from the stock DPF.
I don't get it....

I'm with you Shazzle. if it's a fake DPF to fool the MOT tester it needs to look more like the stock DPF. I don't think that will fool them.

Seen one site selling for £340

Diesels don't need a DPF for MOT anyway, do they? So until they do, why would anyone want this?

Yeah, if you want it to look stock just gut the OEM one.

 

[Jarre]

That's what I thought. Since you can't push the car too hard if you want to maintain low smoke levels, would something like this miltek DPF looking pipe have any benefits over a standard pipe with a gutted DPF?

 

[AndrewJB]

Yes it's got a bigger diameter so better flowing but the original Milltek DPF pipe flows best

But say your car is running DPF delete 210bhp on standard exhaust with DPF internals removed, what's the real world difference going to be like by switching to some form of straight pipe/miltek DPF pipe. Would you really notice that much difference?

I've found out two things over time:

A) the stock diameter is more than sufficient, with no "noticeable" gains, for as much as a CR170 can be pushed at the moment.
B) the flow/back pressure with stock diameter and de-DPF is juuusst right to balance the boost creep which has been part of these things since the pd.

You'd need a pretty good (Revo?) map to make sure that you stay within the MAP limit with mapped boost request + creep.

I know my map isn't that clever. Unfortunately.
Otherwise, yes, 3" tbe and open air intake.
There are reports where the car was grand with normal deDPF, but then "stuttered" or "sudden loss of power" with replacement pipes. Or even with gutting with an aggressive map.

I'd be keen to know from the Revo boys if their map is customised to the levels of creep on each car to really get the best out of them with low-smoke

seems a little pointless to me but im sure people will still buy it, i got a good look under the car while my dpf was being ripped out and to be honest on our cars if you have the plastic under tray still on its actually very hard to even see the dpf, you can only really see the flexi pipe at the bottom of the dpf section
