Did a muffler delete on my 545i
I was bored with the stock exhaust so a friend of mine helped me do a muffler delete. I got 3" stainless pipe, stainless hanger and a 3" in dual 3.5" out tip. He TIG welded all of it then he used a 3" stainless band style clamp so I can change it out easy. It sounds really mean but has some loud drone around 1800-2000 like most v8s. I actually ran a turn down for a few days and that had less drone??!!

If you read my 1st post I was running a 3" turndown for 3 days before this was finished. It had less drone which was strange from my experience in other v8 cars or trucks. Normally a turndown is louder inside but it wasn't the case here. No need for the attitude like I'm a car newb when I also have a Mustang I built that runs 11.9 on street tires. I do have plenty of car knowledge. I may end up adding a resonator to knock the drone down some.
