BMS vs. VRSF
BMS vs. VRSF N54 Downpipes...
Both priced about the same, what is the community's thoughts on the better product? I have not seen much on the BMS unit... Thanks all Last edited by 1911A145; 11-18-2012 at 12:15 AM.. |

I'd go with BMS. Terry has top notch customer service and caters to us 135i guys more.

Check Terry's forums. N54tech. I know he first ordered downpipes and had some guys try them out and when they said fitment was just a tiny bit off he declined to even carry those and found a new supplier where the fitment was guaranteed and that would be these that he is selling now.

I would just look at which one is built better or made fully out of T304 (including the flanges) and then buy that one. |

one thing to take into consideration is that VRSF can be ordered right now, and BMS won't have theirs in for preorder until december....they are both full stainless including flanges

I'm currently between the two as well, so waiting for a member to chime in that has the BMS DPs installed to get their opinion. Like another member mentioned, Terry has great service - and you need to wait until about December 5th to order BMS. Which IMO is not that big of a deal...

The BMS seems to be a nicer design to me a more copied version of the Macht Schnell DP's even down to the placement of the O2 sensors that can actually be a problem of reach requiring you to pull slack or reroute the O2 sensor wiring from around the engine to over it. Minimal work just requiring the removal of the engine cover that most should be familiar with anyway. Either one though will offer about the same results.

^its hard to call it a nicer design when it is nearly identical...only major difference i saw was the extra weld on one of the DP's on the vrsf's...they also have a lifetime warranty which is nice

Stohlen, are you sure the BMS ones taper to 2.5"? The BMS site starts by saying "We are pleased to introduce the BMS N54 full 3" catless downpipes.", emphasis on full. I honestly don't know, I'd like to hear which it is!

I went ahead and decided to get the VRSF DP's. The BMS ones look nicer from their site, but with little community input on actual experience or pictures, I went with the VRSF ones because of the 100% fitment they have had on all the ones they have sent out. So that ment a lot. But I think they will both turn out to be good DP's... |

They all taper to 2.5 inches. There are zero options for a full 3 inch system for this car as I learned today. Custom is the only route I have learned.

Really? Now I'm confused as to which one to buy but at the same time things are starting to make sense.
For example if you read the ar design description "The only TRUE 3" catless downpipes currently on the market! 3" tubing until cat-back flange - all systems currently on the market reduce to 2.5" much closer to the turbocharger." it appears the point they are making is that they are 3" for more of the length than others, but they still taper to 2.5". In that case does anyone have an idea of how the various types compare, which stay at 3" the most? http://www.ardesign.info/store/bmw/b...downpipes.html |

Having a true 3" would being harder to sell, you would need 3" mids or after the dps you would have a bottleneck at the flange where it meets the mids...AR does look to have the smoothest tapper to 2.5"

yup and the guys at VRSF pointed out to me yesterday, it says "up to the flange" Meaning that the flange is 2.5 inches at its opening, and the tubing tapers to that right where the flange is welded.
Essentially they are trying to be very sneaky and somewhat con you into thinking theirs is better from their wording. But honestly, an inch difference in terms of where it tapers isn't gonna make any noticeable difference. Maybe .1 horsepower. If it tapers, it tapers... and inevitably causes a restriction. So as far as I'm concerned they are all the same. Only difference is build quality and material choice. And from what i've seen there is absolutely no reason to buy $899 downpipes when the $329 downpipes are made outta the stainless steel, and probably fit just fine. Tho there are some people out there that buy the $899 downpipes just so they can say they spent $899 on downpipes. |

I never understood why anyone makes exhaust pipes that taper, including oems... it just messes up airflow and velocity and causes havoc in the system. In these days where we are fighting for every horsepower when building a production engine, that would be a real simple way to add a few without adding cost to the process. |

thats true, but the fact is that is a smaller market than the general group of people that will but the product....someone who is really looking for it would be willing to pay a premium to have custom work done

I agree with that, hell now a days a good custom exhaust costs the same as buying one from the aftermarket. Its just hard to find a good shop to do it at.
