Magna Flow Performer 2:1 Exhaust? / 2014 Road King

Hey all -

I am trying to decide which 2:1 exhaust to install on my '14 Road King this winter. I've looked at Dragula 2, FM R&T, Freedom, Magna Flow and others. I am leaning toward the Dragula 2, however I'm curious about the Magna Flow Performer 2:1 (Part No. 7211507 - stainless 3-step header 1 3/4" to 2" to 2 1/4", 2-step baffle, 12mm and 18mm O2 sensor ports, 4" muffler). See youtube:

and

I read one review criticizing the angle of the 18mm O2 bungs on the MF Performer 2:1. My bike is stock except for a Dynojet PV-2. It will probably remain stock except for a K&N AC filter replacement in the stock AC housing. If I recall correctly, the 12mm O2 bungs are used in normal operation and for autotune with the PV-2, and the 18mm bungs are used by dyno tuners using wideband (I'm no expert here...).

Does anyone have any concerns running the MF Performer 2:1 exhaust with the Dynojet PV-2 for any otherwise stock HD 103 HO engine?. I will probably just use the Dynojet PV-2, '2:1 exhaust' map download to start, and then run the autotune with the PV-2. Except for maybe trying a different midrange cam down the road (not sure yet), I'm not planning any future engine mods unless I have a motor meltdown for any reason. In that case, I would want the MF Performer 2:1 to also work well with a rebuilt motor (perhaps a 107ci with moderate mid-range cams).

Anyone running the Magnaflow Performer 2:1? I'd like to see a dyno chart with some TQ/HP curves for this exhaust on an otherwise stock 103. I've searched, but there's not a lot for this system on the forums or the web. I've sent a PM to Magnaflow for some info as well...no reply yet. Some additional sound clips/vids would be nice too.

Thanks all...

bump...

No replies...I guess there are too few users of the Magna Flow Performance 2:1

Magna Flow replied to my PM...they are not providing any dyno chart/results (TQ/HP curves) for this exhaust at this time. Not very encouraging.

Any users willing to share experience (dyno results / PV-2 maps, sound, etc) with this exhaust is appreciated.

Hey Glock35,

Thanks for your reply. I already saw that thread, but thanks anyway. There don't seem to be too many users of the MagnaFlow Performer 2:1. It looks and sounds nice on the 2 youtubes I've seen, but I can't find many reviews on the web...only vendor ads with only 2 reviews. I guess the product hasn't been available that long.

It would be nice to get some dyno curves for torque and horsepower for a stock 103 H.O. motor.

Well, hopefully some other forum members may know something about this exhaust system.

Thanks...
