Wagner catted DP?
Is anyone using the latest euro6 Wagner catted d-pipe? If so are you getting a cel? Any passed obd emmissions check? If so how long have you had it installed for?

According to the Wagner specs for this it is using an HJS 300 cell catalyst
The Fabspoeed catted DP is using the HJS 200 cell catalyst. I have this on my 435 here in PA - no CEL and passes OBD with no problems just as stated by Fabspeed. They are located in PA so they have direct experience... So, I would think if the 200 cell HJS passes - then the 300 cell HJS in the Wagner should also pass But why buy the Wagner when it is priced @ $1450 & not available till 10/25/19, while the Fabspeed which is proven is priced @ $1395 & available right now ??

Correct me if I'm wrong, but I believe the cat in the Wagner for the 435 is not an HJS cat. To my knowledge it is a non HJS euro6 200cell and runs 790 bucks. This is the one I am interested in hearing first hand accounts on as to obd checks and longevity.
I think the Wagner HJS cat is for the 340/440. Last edited by 435gc; 10-17-2019 at 11:35 AM.. |

Yeah stock is 400 from what I've read. I don't know if there is any benefit to going with a 300 cell, especially given the price. I imagine their would be an improvement in sound, but not worth $1400 imo. Last edited by 435gc; 10-17-2019 at 11:27 PM.. |

The Wagner catted for 435 is 300 Cell with Euro6 coating (whatever the heck that is). It is not HJS - so unless that special sauce coating is magical, I would say this would not pass OBD. And in fact it does state that you may get a CEL. No where do they claim that you can pass OBD Emissions, whereas Fabspeed guarantees it https://www.wagner-tuning.com/produc...0001013-6.html https://www.fabspeed.com/bmw-335i-43...-cat-downpipe/ Only DP they carry with actual HJS cat is the one I referred to, but it is for BMW M140(x)i 340i 440i & 540i with B58 engine https://www.wagner-tuning.com/produc...027-hjs-7.html

Also interesting that the Wagner site says their cat is 300 cell, but both Extreme Powerhouse and Top Gear Solutions list the product as having 200 cell cats. Maybe mike@x-ph or jeff@topgearsolutions can comment? Last edited by 435gc; 10-17-2019 at 02:02 PM.. |

It is 400 cell. A FS 200 cell is half the size, hence the advantage.

You sure? ER is claiming 900 cell ceramic for the OEM (at least for the B58 platform):

I just did a search to confirm it. However, I can't speak on the B58 but highly doubt it's high as 900; that sounds like a vendor trying to move some product. Maybe someone with some clout can chime in to verify this. https://europeanautosource.com/evolu...npipe-n55.html Last edited by Poochie; 10-17-2019 at 10:51 PM.. |

I have done a bit more reading and it seems that coating on the internal structure of the cat is standard procedure. The cat is a structure of metal or ceramic and is then coated with precious metals that do the magic. |

Depends I guess on how long it last with out getting CEL, some people or the sales rep wont guaranteed it but will point out members that have had it supposedly a long time with out a cel, probably to sell it.. My Wagner DP supposedly with upgraded cell lasted about 2 months before I got a CEL, cost was less then fabspeed. I regretted not going Fabspeed but oh well. Don't have to smog till 2022 so not worry about it. Been thinking about catless.

I ran the 200 cell VSRF (5" cat) and got CEL's everyday. It was replaced (fitment issues) with a ER 200 cell (4" cat), and have never had another CEL (knock on wood). One thing to note (from my experiences), the larger the diameter, the larger the holes in the cat (assuming same cell count). So if OEM is 400 cell, and the aftermarket is 300 cell, but larger diameter, the cells are larger and will flow more. |

What kind of fit issues would make you want to uninstall after already having it installed...?

B58 DP has 2 chambers 600 & 400 - totalling 1000cpi “blockage” just downstream of the turbo.
Swapping out to 200 or 300cpi DP will help throttle response as turbo builds boost faster and no doubt turbo will be able to cope with load-control demands from DME as it will generate less hea |

I was just commenting as the VSRF was 200 larger cells than the ER 200 cell. |

I'm not sure that's right. A larger diameter cat(say 5 inches)that is 200 cell would have the same size cells as a smaller diameter cat(say 4 inches). The cell count determines the sizes of the cells. Whether the cat is 3 inches or 10 inches in diameter. If it is 200 cell the size of the cells/holes would be the same. Now a larger diameter cat would flow more, but it would be because you have a larger "bandwidth" not larger cells. |
