Active Autowerke keeps updating its catalog, which has led to so many midpipe designs. While more options are a good thing, and im glad they keep improving this platform, it has reached a point where it can be confusing. I'm not saying this isn't good; I'm happy to see them pushing the boundaries. But it's time for a dedicated thread to clarify the differences.

Let's start first with the original designs.

1- the X-Pipe. This midpipe is offered as a straight or catted pipe. The X-pipe sound is exotic and has a high pitch. Perfect for customers wanting an aggressive sound and do not mind the rasp


2- the single midpipe. It is offered as a straight pipe or resonated. this midpipe offers the cleanest tone with a deep midrange sound and zero rasp or drone


3- The equal length. This midpipe sound is between the single and the X-pipe; it's not as clean as the single but much more aggressive with a deep midrange sound and aggressive high RPM tone. And although raspy, it's not as raspy as the X-pipe.

Gen 1 was released as a straight pipe with an excellent sound, but one drawback was the cold start (it had a metallic sound to it) and the added rasp on high RPM.

Gen 2 is released as a resonated version of Gen 1 to keep the pros of the equal length but minimize the cons.

Gen 2 with the added resonator is the same as the regular Gen 2 but adds another resonator to the midpipe to lower the tone even more and eliminate the unwanted noise.

Please note that Gen 1 and Gen 2 are available for purchase. At this time, Active Autowerke has not discontinued any of its midpipe options.

You will also notice a listing that says equal length upgrade; this listing is for customers that already have the equal length Gen 1 and want to upgrade to the Gen 2. If you are on stock midpipe, please do not select this listing thinking you will be getting the full Gen 2 midpipe for a fraction of the price. Instead, you will receive only the parts needed for the Gen 1 upgrade.

Hope we will have Gen 2 and Gen 2 with extra resonator video clips soon!

Kudos to them for the innovations in bringing more to the market

Here is AA Gen 2 resonated cat-back with catless downpipes on the black G80.

I encourage everyone to use this thread as a hub for sharing sound clips of different Active Autowerke setups. This will make it easier for users to choose the right AA exhaust for them
