Borla Exhaust - 1M initial thoughts
Hi Everyone,
I'd like to share my initial experiences with the upcoming new Borla axle back muffler for the BMW 1-M. In January, I had the great oportunity to loan the guys at Borla my car to test fit some new prototype products they are working on specifically for the 1-M. I eagerly picked up the car last Friday and can report that I'm very happy with the results! Motivation: Since owning the car, I have felt that the stock car has a fairly muted exhaust note. I once heard that something approaching 50% of a person's emotional impression of "speed" and "high performance" is tied into the noise they hear their vehicle making. Having come from a 2004 VW R32, I felt that the 1-M could use a more visceral exhaust experience but also wanted something that was livable for everyday life. This was my motivation for being a test guinea pig! Quick thoughts after 200 miles: - The new exhaust increases exhaust volume under power while maintaining a refined sound and timber similar to the stock muffler with no noticeable resonance, rattles, or heavy metallic notes - Outside the vehicle, the muffler makes the exhaust note more prominent (compared to the engine mechanical noise or turbo noise) by adding a healthy amount of "growl" - Inside the vehicle with windows down, exhaust note sounds great making heel/toe down shifts more rewarding =) - Inside with windows up sounds amazingly composed and quiet at cruise throttle. It's still very quiet inside because of the great sound deadening of the 1-M. I actually believe the 2100-2400RPM highway cruise "drone" is reduced compared to stock. I'll take it! No other noticeable cruise "drones" at other highway RPMs. - The butt-dyno reports that the car still hauls buns! - Exhaust tips look very good with a similar design, diameter and fit in the bumper cover to stock. - The muffler uses the stock exhaust mounts and exhaust clamp location (bolt on mod) - Have no problems "sneaking around" town and the neighborhood. The new exhaust can be easily driven in a manner to not draw attention toward your car. The fact that I'm driving a bright orange 1-M... not much I can do about that! Based on my first few days, I think their new muffler is really how the car should have been equipped from the factory. I know a lot of testing and development time went into this muffler and it shows. I'm planning on attending the 1-M meet up Feb 26 in southern California. I'm looking forward to hearing the relative differences between the Borla and another stock vehicle in person and also recording a quality back to back sound file to share on the forums. Here are a few photos and a brief video link: ***Edit*** (fixed video link) https://picasaweb.google.com/JohnnyCakes75/Borla_Exhaust_020412?authuser=0&authkey=Gv1sRgCMPg u6qYzfqonwE&feat=directlink#5706236164733799698 - JohnnyCakes Last edited by JohnnyCakes; 07-31-2013 at 12:20 AM.. |

Nice review! Are those fins part of the muffler? Or are they part of a separate aero kit? It's hard to tell from the pictures... Either way it looks nice!

Regarding the fins, stay tuned for more details on our (optional) exhaust-diffuser component... |

Yes the diffusor, can we have some close up photos of the diffusor and the tips from different angels please?
Other questions for the producer and/or reviewer: - How is the cold start up sound compared to stock? - Any registered power gains? - Is the diffusor tested aerodynamically and brings any benefits regarding the lift at the rear of the car or just esthetics? Thanks in advance. Last edited by ozinaldo; 02-07-2012 at 09:21 AM.. |

Thanks for the review. The only comment I have is if you really think the 1M has great sound deadening, I hate to hear what you consider average or good.

We are working closely with an aerodynamicist on our exhaust-diffuser development to optimize performance of this unique product. We'll have more details at the SoCal 1M GTG later this month. I can share some information for those interested: - This exhaust-diffuser is an option to our Borla ATAK system, PN-11820 - This integrated option mounts directly to this exhaust system - There is no drilling required or the need to remove any stock fasteners of your 1M for installation - It does not contact any surface of your 1M - It is styled specifically for your 1M in metal to compliment our exhaust tips - It is designed to improve exterior air-flow with our exhaust system (not a full aero solution to reduce lift) - Did I mention it looks cool? |

Thanks for posting your impressions and a video! It sounds great!
Alvin T do you have any idea on prices yet?

Nice!! I really like Borla Exhausts. I usually choose them when I think on modifying exhaust systems. I recently fitted their catback setup on a MkV R32 and love how it changed the car. Not only in the performance/sound aspect, it also makes a huge upgrade as a estetic modificacion.
Can someone post closer shots of the tips? How about their dimensions vs the OEM ones? 80mm?? Will you offer a full turbo back system? |

Me too. Have the N55 midpipe, impatiently waiting on the exhaust.
