Look on eBay. You can probably get one for about $75 shipped.

Tanks TurboM,
I'll try and copy that and plug the second hole into the Helmholz chamber as well. I have easy access to some gear and the plug can easily be removed again. This is only a test as my mind is 60-40 against getting a positive result. We'll see when I get to it. /Krelle |

I've been really interested in this type of mod since I saw a thread where M3's were having it done.
What I'm not quite clear on is how sealing up all the holes in the muffler produces less drone and a different sound than straight piping. |

It's louder but not to the point where it will emit unbearable drone.

and more importantly (for me) the exhaust note is almost inaudible while cruising. It does get much louder once you pass about 50% throttle. This is definitely not the case with a straight pipe.

I believe the guys that were doing it on e9x M3 were from Canada. They charged $400 plus your muffler as a core. For the sound it's a pretty good bargain, especially with how much car backs cost now days.

Now that I look at the picture again, it appears that there is an additional pipe the runs from chamber 1 into 2 that you have no touched. Is that correct? |

Someone in an earlier post mentioned they were planning on plugging this hole as well. I advise against this because essentially what you will just end up with is straight pipes. No sound can escape into the Helmholtz chamber hence it will drone and defeating the purpose I set out for. At this point if he's gonna plug up that hole as well you may as well cut the muffler off and just straight pipe it.
