How did you get four holes? Once I got my first one done, any further attempts just slip into the first hole. Mine is about 7/8"/22mm.

I used a large flat head screwdriver and a hammer to make a small dent that I could use to hold an M12 bolt in position I used to punch out the holes.


Edit: After I took the photo I punched two more holes.
The modded stock Boxster S muffler with 200 cell cats had only tiny bit more drone and rasp than the FVD Brombacher sound edition muffler I have now, otherwise the exhaust sound is very similar.
