Until you rev it up....

Honestly, just do it. Like the OP said earlier its 100 bucks to replace it ( or you can buy mine for $75, its for sale) I personally think that the stock exhaust sounds like crap with all the rasp, and to me it makes the car sound different but still like an M3 (just amplified) but still lik crap. Almost like someone that has no muffler b.c it was rusted of....

Seems like you're in VA. If you want, I have a stock muffler too that I'd be willing to cut up and experiment with. That way we can do 2 different types of designs instead of one. LMK

Im disappointed with the sound from my Borla mufflers. Well not intirely true, sometimes I love it, and sometimes I feel it's to childish, Boy racer, tin can, cheap sounding.. Haha. If this at all turns out to sound stock with a little more umphh, I would be all over it.

Unfortunatly, our cars will never have that deep throaty v8 growl, Wich I love.

It's a shame I gave my oem muffler away for free, could of been a nice guinea pig.

For those with limited knowledge of the E46 M3:

OE Muffler: 60lbs
CSL Muffler: 55lbs
HPF Muffler: 6 lbs (one of many lightweight aftermarket if you're looking for weight savings).
Source: http://www.horsepowerfreaks.com/part...Titanium/13483
... and I have a CSL muffler weighed/installed
I would call that 50lbs+ actually.

OE Battery: 49lbs
CSL Battery: 34lbs
Braille Racing Battery: 21lbs
Hi/Low difference ~ 30lbs

+1 OP, thank you for clarifying..

And yes, I understood gutting the fiber wouldn't be a weight reduction issue earlier.. I think there's also some kind of glass pack in there in addition to the fiber as I've seen a damaged/dented muffler and heard particulate matter rattling around. There may be a bit more to the sound insulation, but I've never seen one cut open. Interested to see where this goes.

Im working with curiouz-g up above regarding the stock muffler. After our finals, we will begin discussing a possible design. We live fairly close to each other so fabbing something up shouldnt be a problem.

Also note that the E46f weblink contains pictures of the cut open muffler

Bump, now that finals are complete and Im back home studying for the GRE and working, I have some down time to put towards this project. I talked with a friend who has various tools for different applications. He has a torch but doesnt recommend it on the muffler, but insisted on a sharp rotating blade that could cut the steel. Im trying to keep the cut clean and square so as to weld it back up with minimal damage to the muffler casing itself. Open to suggestions.

Ill also be taking pictures of the process as I go along. If all else fails and I dont like the end product, Ill scrap it and buy another OEM muffler for cheap.
