2.0 TDI exhaust

[Vicbitter]

greg his car doesnt have a DPF that lucky bugger

i have the 103kw with apparently with no dpf (i read in the dpf thread)

so....i could put an aftermarket muffler on it relatively easy with no major probs?

[Greg Roles]

Absolutely VB, you could do a full turbo back exhaust if you really wanted to.

I haven't measured it yet but i think i got the 2.25" piping.
I really wanna get rid of the stock muffler and attach something better!
Would i really get much of a gain in anything? other than looks.

[Greg Roles]

Possibly a bit better response, but I would expect little from a simple muffler delete. I am of the opinion that the CRD does come with DPF, as ALL new VW diesels to most counties do from now on to meet the new forthcoming emission rules. If anything that's by far the biggest exhaust restriction, and not an easy thing to delete. Better to await a chip for your car if you want some more berries.

Looks like you have the typical VW huge pancake rear muff. I'd guess you have a resonator before the rear axle, in which case I'd be tempted to do a delete anyhow...what I'm planning for sure.

Shame you got ripped off at 2.25, my VW is 2.5 mandrel all the way baby!

Funny thing is, i was reading the manual and no where does it state it's got a dpf!! Mentions cat converters but no particle filters......

I even called jeep, and on their systems there is no mention of dpf.
So it leads me to believe if it has no dpf, (gotta be a tdi then?) less restriction on a exhaust mod.
I guess i would have to wait till the warranty runs out to do it 3 yrs from now......

PD or CRD VW calls their diesel engines TDI regardless.
Both can have DPF.

I had an exhaust place experiement on my car for 2 weeks to try and get a note out of it. Went through 10 resonators and did everything imaginable. Still no noticeable difference. But it took a fair chunk of weight out.

Any more grunt?

Any more grunt?

No, nothing I could notice.

[Greg Roles]

very interesting, seems that the stock exhaust, at least post DPF is flowing very well. It certainly "looks" good, 2.5" and mandrel bends, so it appears the stock muff and resonator are flowing well if swaping gave no noticable effect.

Damn!

[comfortline]

Cogdoc,

Probably the DPF is the major restriction.

DPF delete anyone?

[Greg Roles]

Absolutely is, but you have to give it to VW that they can still make the GT perform so well stock WITH an ultra restrictive DPF.

It can be removed, but personally I'm not too keen to start smoking everyone out, I hate folowing smokey diesels.

[comfortline]

I think its a hoot. You deploy the smokescreen, and then you vanish.

[Vicbitter]

Punch it, smoke it, leave 'em behind

Trouble is, every time you do that you are adding another person to the majority who currently think - "Ugh ! Diesels are horrible polluting things, next time a politician wants to totally ban them I'll give them my vote." And you know where that will end up - no diesels allowed on the road at all
