It is important for the gasses to be hot enough to get the cat to do the chemical reaction. The gasses cool as the travel down the downpipe and then more so when they are in the exhaust (past the DP's outlet). The more forward the better is my point. This is why it is discussed by some of us to gut the DPF but use the DOC built into the front of it. Other point is diesel ex gasses are cooler than gasoline ex gasses.

Actually I was thinking of the bypass being between the turbine exit and the DOC entrance so when "off roading" one could bypass the exhaust restriction...

Good point. I want the cat along the bottom of the car and not up there where the DPF used to be to make it easy to service if I ever need to.

Perhaps exhaust wrap to keep the heat into the cat?

120 pages - and what I gather is that Ecotune is not well received in the North American market because of the poor fitting pipe and the ECU flash causing or masking other codes.

Can someone advise if these problems are specific to the North American models only as I have a European 330D?

What replacement pipe is everyone using? The forum user that supplied some people with a pipe seems to be no longer active.

Thank you.

Thanks Puerto Rican 335d.

What about the quality of the Ecotune pipe? It has been mentioned some difficulty aligning the faces and installing the V-clamp?

Fit was a US issue. However, north american tuners are now making quite a bit more power than the ecotune seems to make so there wouldnt be much incentive to use them at this point anyway. Ecotune quoted power at engine is about equal to what we are seeing at the wheels with these tunes, thats a huge difference in actual power.

The problem wasn't the rear flange nor the V band flange. It was the orientation of the O2 sensor bung. Looking aftward and using clock dial reference, it was pointing at about 10:30 to 11:00 position and needed to be rolled out to more like 9 o'clock. Bohl diesel moved mine. [once again, why the heck was he banned?]. He also cut off the pressure sensor tubes and welded little nubs over to seal them.

Thank you Hooper & BB_cuda for the feedback.

I have only heard positive reviews from Australian owners about the pipe and the tune.

I had a look on the Bohl Diesel website and it has a picture of the DPF pipe which I noticed earlier in this thread. The workmanship on the replacement pipe appears to be of a high standard which initially was why I posted on this thread.

I understand that most North American (and South American) have 335D's but this model was only imported into Australia for a short period and the majority are 320D and 330D's here. The emission standards in Australia follow the Euro limits with Euro 5 currently the standard. This may explain why it appears why the European vehicle has three orifices and the N & S American appears to have only two.

Thanks again to everyone for their valued input.

Hi Ken- I recently learned Bohl diesel is no longer making pipes for general sales over internet. He told me that he will sell pipe for customers that come to his shop for work (upstate New York). I'm guessing that would be no for you since your in Australia. Good luck with your search.

I guess that is why I never heard back from him after I inquired about a DP a few weeks ago. Would have been nice to get an email reply stating that though....

A few months ago I emailed asking and never got a reply. Don't feel bad.

I hope all is OK. He pioneered a bunch and is still working on great things we enjoy as mods on our vehicles. But while once praised for customer service, I have also had no luck getting in touch. I am about an hour and half drive away from said shop and it would be my pleasure to have him wrench on the car. Next time I am up near Albany, I will try to stop by and maybe introduce myself.

I've heard such good things about him, but have never had any actual contact. Maybe one day he'll come back around. I don't hold grudges for this kind of thing too easily.

Jess has moved on to bigger and better things on engines people depend on for a living. He's even sold his car but will always have the X5. I think all of us who have had contact with him and now reap the benefits of his skills would agree that he is a class act.

I'm thinking I'll put it after the first bend off the down pipe so its easy to access should I ever need to hack it out to replace.

Did you end up installing this and did it meet your expectations? Pro's / observed Con's.

Thanks!

Yes, I did install it!

Pros:
- Reduced rank exhaust smell when idling in traffic.
- Less of a cloud of death behind me during regular driving.

Cons:
- Still smells like @$$. But not as bad as when it was straight pipe. I still have to roll up the windows and turn off the air if I idle too long in traffic as the smell just kind of starts wafting around the car. (depends on the direction of wind too.)

Did it meet my expectations? I think it'd be hard to compare to the lack of any unpleasant smells that all the stock emissions equipment took care of. But my equipment was all failing and doing the ABC delete and getting tuned was the cheaper option.

That said, the cat did help with reducing the smell and visible exhaust smoke. Better than nothing?

I don't really think the smell is that bad. Sure, I wouldn't want to sit around inhaling it all day, but I was in a garage with the car idling for about 5 minutes and it wasn't too bad(Open door, but the back end was facing the enclosed side the the gas lingered longer). Certainly not as bad as that ammonia smell you got with the stock emissions in place. Smell is noticeable in traffic while idling or sitting at a stop light, windows up or down, but not bad enough to make me roll up the windows or shut off the A/C.
