Do you guys have sound clips for this slip on system? All I could find is a few clips for the evolution system. And are those hp and torque increase values accurate? I know on their website they suggest these increased values are with the optional wireless kit and open valves. I was also wondering whether BMW will come up with a performance system similar to the one developed for the M3's?

Many thanks and cheers!

P.S. sorry if this is a repost.

+1 - I hope BMW comes up with a performance exhaust as well- I love the sound of the PE for the 135i!

This is direct bolt on and uses the stock hoses/couplers. No trimming or modifications required.

NB. The spike at 2750RPM is caused by the car being released after being held under load on the dyno. It is not present while driving the car on the road.

I called CPE a few weeks ago and the system is still in development. They are still making some final tweaks to it to better the sound is what I was told. Currently, the muffler drones too much and is on the loud end of the spectrum. I think they want to tone it down a bit which is likely a good thing.

Megan Racing should be cheap. From the video it sounds awesome as well!

Cpe downpipes are much cheaper than Akra and they serve the same purpose. They make mid-pipes as well, or you could go with Berk or N55 midpipes.

Borla review

Borla review-
http://www.1addicts.com/forums/showthread.php?t=645294

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:

Intstallation on a scale of 1 (easiest) to 10 (hardest) I'd rate the Magnaflow a 3. Install required a 14mm socket and a 15mm socket.
Comparison to the stock exhaust:
Magaflow feels about 2 - 3 lbs heavier.
Stock exhaust sounds better at start-up, under load and overall. I prefer the slight rasp and metallic sound of the stock system, the Magnaflow is quieter at start-up and while driving.
Magaflow has less drone.
Butt dyno felt no performance difference in systems.
This exhaust is much more mellow than stock, for those considering a new exhaust I'd look elsewhere.

So many exhausts for the 1M. Thought no vendors were interested in creating aftermarket products for the car. Now... the question is which exhaust to get.....
