Downpipe for 1M???
Guys,
I've the eisenmann exhaust on my 1M and this week I'll install the midpipe... I wish to buy and install the downpipe too...but some people told me if I do that, I'll have problems with a sensor and a light will be on my dashboard, and I could have some problems (it's seems that the 335 and the 135 had these problems...) So I want to ask, is this real?Can I buy and install a downpipe on the 1M without have any problems? If there is no problem, what brand do you propose for downpipe? Thanks... |

Different high flow catted pipe, but the result is still the same. They cost more and they have a high failure rate which will degrade in about a year or two. Return them while you can and save money by buying a set of catless downpipes. You can suppress the CEL by having an aftermarket tune on it. My Cobb Stage 2+ map suppresses this CEL even though I have a set of catless downpipes on my 135i or use the BMS downpipe fix. |

I have Akra Slip-on, Akra wireless valve, N55 midpipes and JB4.
Ordered PLM 3" catless downpipes yesterday for 395$(!) and will post a complete review of installation, fitment and sound with both pictures and videos.

Meisterschaft now has a line of 3" down pipes for the N54. I think I might give these a go and change over to resonated mids.

I rock the VRSF 3" Catless on mine and love them. You will get a SES light no matter what brand aftermarket catted or catless downpipes.

What about those of us whose states require inspections? I want to do a dp, but I don't want to have to swap it out when I go in for an inspection every year...
Considering N55 mids too... so I think I would be fully catless?? I feel like that may be a recipe for disaster. |

We have installed catless AR 3" DP. At Stage 2 GIAC software flash, it is worth about 8-12 whp over OEM. Catted version will be a bit less. The OEM DP's are actually very efficient and aren't the same ones BMW installed on the 135i and 335i.
