Throw a resonator in there and it will get rid of the rasp while still sounding nice.
Thinking about it. Going to drive it like this for a couple months to see how I like it. When I had the stock muffler still on with the DPF delete it was a little to quiet for my liking. A little drone at 60mph, very little at 70, and almost none at 80.

I put a high flow cat to deal with the smell and then kept the stock muffler as I didn't want to get pulled over. Exhaust tickets are a huge thing around here, so now I'm basically as quiet as stock.

Really? Knock on wood, but I guess I've been lucky, with straight pipes on everything except the recent vehicles.

I like the idea of the delete but I think that video has a little bit too much rasp for my liking. Like a little more turbo whistle instead. I really do look forward to the day I can do this mod.
You probably won't get any more turbo noise with such a small turbocharger doing so much work.

Just an FYI for those interested... here's a recent UOA for my Malone/Rawtek TDI taken at 30k miles with about 25k miles since the install.

Bumping an old thread. All my issues with this car are emissions related. DEF Tank heater, NOX sensor, EGR valves, etcetera. Since it seems to be $500-ish every time... I'm thinking deleting the emissions stuff might make sense. Plus a bit more power and MPG is always a good thing.

Coffee, you're in my area, sorta. Any tips now that you've been running this for a while?

Last I heard from Coffeemade, he said he wouldn't do it again if he had the chance to do it over. I'll ping him to check this thread.

Cost me $1200 for a delete at 30k miles after a turbo failure and exhaust flap failure. I saw the writing on the wall. Now at 95k miles and not one emissions issue. I wouldn't own any diesel from any manufacturer with an intact dpf system. Way too unreliable and expensive. If the epa really wants to push this crap, they need to make a compromise where it's reliable and reasonably priced. Otherwise people will continue to remove them. I wouldn't have taken mine off until the 120k replacement if it wasn't such a problematic system. Almost all of my cars issues revolved around that system I'm some way. Passats with the dpf installed are also having high aluminum in their oil analysis where mine is almost Nil.

206ppm aluminum this last time its bending the minds of blackstone as they think my piston skirts should have already been worn off the piston. They said they haven't seen anything this high (short of a blown engine) in the history of automotive oil analysis
Telsa Model S with a government subsidized solar farm anyone?

My theory is that it's coming from the oem turbocharger and being injested in the intake. Mine had a ton of end to end play when I removed it. The housing appears to be worn from contact with the impeller. I'll try to get some pics next week.

What did you use? $1200 would be well worth it. Is that hardware ad tune?

I deleted mine and would definitely do it again. I did leave the muffler in place and the does smell when at idle. However, you cannot smell it inside the cabin when sitting in traffic or driving

Yeah Blackstone really doesn't know what to think about all of this, but they sure are pulling their hair out about it. It's obviously not catastrophic, as we haven't seen any engine failures yet that I'm aware of.

Some speculate that the new design of the EGR cooler is causing the high aluminum. Whatever it is, I'm not worried about it at all.

I would like to know this as well. The only option I know of now is Rawtek, which will cost me over $1k in parts and $1150+rental for the malone tune.
It was back in 2013 so the prices were a little lower back then I think. 1200 was for parts. My car is a manual so it didn't need the malone dsg tune which was less and the downpipe was from diesel dubs. I still think it's well spent money vs dealing with failures out of warranty. I'm already at 100000 so my filter would be nearing replacement. And removal allows me to run my favorite Rotella T6 synthetic!

Thanks for the info. Has dieseldubs gone out of business? I know they were supposed to have the better priced option but I cant find anything about them any more.

I currently have the adblue heater problem and theres no way I'm dumping money into that emissions system with all the inevitable problems I'll have to deal with down the road, I'd rather solve the problem and get it all removed. Right now I'm waiting for a dieselgate resolution to move forward with ripping it all out. I'm sure there's a really low chance of it happening, but I would hate to spend the time and money removing the emissions system just to have to sell my car back to VW.

Looks like DieselDubs changed their name as they seem to handle diesel Mercedes-Benz, BMW and Sprinter vhicles now in addition to VW/Audi diesels. Entered "http://www.dieseldubs.com" in my browser and ended up with:

https://www.germandieselmotorwerks.com/

Should be able to shoot them an email or call to find out about the NMS exhaust.

So someone asked me to update this thread. I'm still running the tune, but with many different things in life I'm tired of worrying about what if's and I plan to sell the car in the summer or later this year. I have 97K and it runs great just other priorities in my life and I want an SUV.

So the number one question is would I do it all over again. No, while I have met a lot of great people along the way, this car has been a distraction. I hate the seats, even with cc seats it's still not as comfortable as other vehicles out there for tall people with long legs.

Just go to buzzken exhaust and get yours there. No sense of paying extra for a rawtek exhaust (which germandieselmotorwerks sells I believe ). Accompany that with a malone tune and off you go. If you have a manual I would suggest upgrading the pressure plate and clutch disc. Not necessarily needed if you arent mashing it all the time but over time, IMO, it will eventually need replaced as that is the weak link. just my .02

I too am now taking the off-road only plunge with my '13 NMS since I decided to keep it. I am dumping some unexpected new found funds into the car, nothing coming out of savings so what the heck.
I ordered everything today. I ordered the Garrett CR190 turbo kit with just a straight pipe, the down pipe/dpf delete, and a Malone stage 3.65 tune upgrade. I could not find anyone else with this setup yet to help in making the decision to go this route so I guess I am taking one for the team. wish me luck!
I also ordered a big brake kit, new Bilstein suspension, and a kick ass sound system that will blow my hair back. It was either all that or wait for the new cheaper Tesla that is supposed to be ready to buy in a couple years. I just really want a car I do not have to fuel up once a week.

I currently have a Malone stage II with the DSG tune, an aFe cat back, and aFe intake. Honestly I could not really tell much of a difference from stock, if any, in the lower gears other then it does not sign off as early. 4th-5th seem a little taller, a little nicer. I do feel a little bit more torque on long steep climbs. I honestly feel the DSG tune did more for the car then the stage II, buts that's just me.
That said. I will do my best to articulate my impressions of the new config once I get it up and going and to gather as much real data as possible.

Here is the kit, I am sure you all have seen it by now http://www.fixmyvw.com/garrett-cr190-gtd-turbo-for-cr-passat-tdi-and-2015-tdis/

Im running 3.5 with a CR170 and it's a world of difference from stock and even stage 2. No more running out of steam before 4k rpms. Pulls hard through about 4200

The stock turbo is a severely limiting factor. Without upgrading the turbo, I don't think it's worth spending money on an engine tune.

OK this is good, 2 very encouraging posts. Thank you gentlemen!

I am hoping to do the install myself but without free reign over a rack the thought of working under jack stands does not sound fun. When everything arrives I will re-evaluate, see how I feel about tearing into this project myself or taking it ti a shop

The service advisors at my local VW dealer suggested that modding the cars after the fix would be the best path forward if you want to keep your car.

I hope to undertake something similar once the fix is identified and if I decide to keep my car. Do these mods cause a check engine light or throw any readiness codes? Thanks, John
