Installed the Daehler axleback exhaust and valve controller today. Install was pretty easy just took some time to cut out the plastic bits it fit in the new exhaust tips. Also takes a bit to get it all lined up evenly. The instructions suck and are missing steps but still wasn't difficult.

As far as sound, its def a bit deeper with the valves open but not nearly as loud as I had hoped. Im stock so I guess my next step is downpipes... just not sure if I should go with just the secondary pipes or fully send with primary too. I'd like it louder but not straight pipe loud. Maybe race catted primaries and secondaries will be good enough just not sure. Kind bummed its not louder with just the axleback. Anyone else have similar expectations?


Ofc I'm coming from a catless F80 with AA single mid and Eisennman axleback and that's the perfect loudness for me.

replaced all cats with downpipes and it sounds deep and throat like it should! Highly recommend!
