With the DPF removed the exhaust is really free flowing "no restrictions".
Except for the stage two tune, the DPF delete and mid pipe the motor is stock.
Remember there are two EGR systems a high pressure and a low pressure.
The high pressure is from the manifold pre turbine to right before the throttle body (yes these have a throttle body). Back pressure in the manifold forces the exhaust into the intake stream. This would be retained with a DPF delete of any kind.
The low pressure is from after the DPF but before the second 2 cats, goes to a cooler mounted on the back of the block and then to the turbo inlet on the low pressure side. This system works by closing a flapper downstream (between the last 2 cats I think maybe after I'm blanking).
In order to retain the low pressure EGR you would also need to retain the flapper or it would not work properly. Actually from what I can tell just removing the flapper disables the low pressure EGR actuator from even opening. The flapper is a dual vband section in the middle of hte exhaust and the branch off to the cooler for the gases is also a vband fitting. Its not impossible to retain it but it would add significantly to the cost and complication of building the exhaust.
The low pressure EGR also seems to be the cause of some EGR problems that are popping up on higher mileage cars lately. Outside US canada I don't believe any of them have the low pressure egr.
Obviously emissions reasons to maintain it just point out some of the hurdles.
In car driving with the DPF/EGR delete and stock cat back I would say its roughly 2 db louder tops, you can hear it more but it is not intrusive and really only under load or change in throttle not cruising.
Heard one finally pulling away from me the other day, the sound is a little ugly, not as deep and imposing as say a PS or a cummins. But out of the whistle is very distinct and sounds awesome. Stock someone might now be sure if its a diesel or not, with the DPF/egr delete and stock cat back it is now very clear that it is.
It sounds a little louder then in person. The car was in the garage and the shot from the back was done about 3 feet away.
I tried to enhance the sound in final cut. Might have done it a little too much
Last week a Vortex member came by to visit me at the shop with his Jetta TDi He has the Rawtek system with no muffler and a resonator. That was loud. Sounds good.
good info Chris
doing some research.. I see
I installed same setup on a mkvi jetta last week after work for a dude at work (50$ labor fee, lol)
but that was my 4th or 5th install. So pretty easy getting it all out and back in. Sounds good overall though some fitment issues for a couple things but overall nice stuff.
Bunch of stuff.
Man those spyder headlights make baby goats cry.
Revo Tune / afe Intake / Neuspeed Turbo Exit Pipe / Mufflerectomy / ST Coils / Golf R Steering Wheel & Shifter / DG Short Shift Kit / RNS-510 / MKV R32 Brakes Front & Rear / Euro Golf R HIDs / Nurburgrings / S53 Whispbars
I know they're not the most popular mod in the universe, but so far, they've been great and I get a lot of compliments on them. Price was right too!
If I were to do it again, i would probably get Ed's lights, but what's done is done for now. You've got to admit that they are WAY better than the stock POS reflector headlights.
I will change the subject lol, I think I found some wheels I want, BBS RS, 17" I believe they are 8.5" wide and 37 offset, will that work for our JSW?
Since we do some city driving with it and the roads suck, was thinking of using the same size tire that is on the stock 17" portos, no good? Input appreciated!
played out or not.. they look good
I've seen pics of a rear cupholder. In the center console but for the rear passengers. My 2011 JSW just has a little useless pocket below the rear HVAC vent in the console.
Was the cupholder that would go there a euro only thing? Can you buy and install it in the US rear center console w/o replacing the whole assembly or losing the rear air vent?
Ok, found this one at ECS under the MK V Jetta....
Actually looks very similar to the one in my wifes 2011 Tiguan, are they the same?
