So Im looking to possibly do a 1M conversion on my 08 135i and seeing as the price of the battery/exhaust parts for the project are astronomical, I figured a fake quad setup might be worth looking into.

As such I have a Maddad Whisper exhaust (the nicest sounding IMO) that I would possibly be willing to work something out for a Quad setup. Not sure who has what, but let me know if you're interested and I can send pics. System is currently on the car and is in great shape overall.

Only interested in the quad setups, otherwise I'll likely keep the single sided for now.

This might more more of an interesting tangent, but I also have a MadDad Whisper Exhaust.
I wonder how it would sound if an exhaust shop combined two MadDad's together into a quad exhaust setup...

Can you post a video of the sound?

I thought about trying to do this myself, however that would likely result in having to do do the 1M battery box mod anyway to clear the second muffler as there is definitely not room to mount one of these on the passenger side
