OEM exhaust mod questions
So from what I understand there are 4 chambers in the exhaust each with a perforated pipe.
If you just want the exhaust to sound a little louder and a lot better, you replace the perforated pipe with a straight one in the INNER 2 chambers. If you want the exhaust to sound a lot louder, you replace the perforated pipe in all the chambers. I just want to make sure everything is right.

I read through the entire original thread last night and I didnt see any videos of what happens when you do what the second diagram shows above. Does anyone have links to one?

It didn't occur to me until now that what you did is EXACTLY what Dinan mufflers look like indeed . I gave them too much credit for the design . And your car sounds just like those... with real tips and much better fit. Hey, there's no need to reuse the packing material without absorption holes on the pipes. But it'd be nice to have both to 'absorb' the raspiness.

Thanks for the video. A friend of mine is making a race car M3 and the stock exhaust is off the car. If someone is interested, let me know! Otherwise I'm gonna buy it and have it modded so its ready for when I get my M.
