2002 E46 M3 // Build Thread


Recommended Posts

Did trans fluid change, oil change, cabin air filter and intake filter change and took it out for a quick shakedown this weekend. Of course found more broken stuff. Ordered UUC trans mounts and all new bushings/gaskets for the shifter carrier to go with the UUC EVO 3 when I install it. Rotors seemed a bit warped too with heavy braking, dang.

Exciting updates! Taillights look great, can't wait to hear those headers.

Same!! Here's a couple clips of my end goal:

The setup is fabspeed headers, stock section 1, resonated x pipe and a top speed muffler. Never even knew the S54 could sound like this, but JEESH

I’m not a huge S54 guy because of the typical sound of them, but that video right there changed my mind.

All videos with really good sounding S54s are deepfakes of an E36 M3 with a pitch adjustment /s

It is entirely possible to have a great sounding S54 but I have yet to find a quiet setup that sounds good enough to spend money on. Loud enough to actually hear it while driving but quiet enough to hear the induction sound and not be a nuissance.

 

When you see inside the stock muffler its a bit baffling at how they arrived at such a design.

Most of the nice sounding ones are running catless headers+resonators with an aftermarket muffler and are just stupid loud. It seems that adding back quieter mufflers just seems to cut the noise but maintain the rasp, which is exactly what I would want to get away from. I wonder if going to quad resonators, x-pipe, catless headers, and a moderately quiet muffler would be the solution?

 

Have any pics of said muffler guts?

note the perforated pipes

Interestingly the Z4M seems to have better luck with muffler options that sound good.

The stock exhaust sound isnt BAD, it is unique if not just a little bit exotic, but it isnt a sound that gives James May a fizzing sensation. 

The risk comes with modified exhaust as you can really ruin it, making it worse than stock. 

@pynacl  I wish you godspeed, just not a Godspeed exhaust

Totally agree with what you and @P_Roloff said that it’s so hard to find a great sound that won’t rattle peoples brains around you. I’m going to just keep experimenting until I get it just right. For me it’s a weekend spirited driving toy, so a lil too loud is okay, long as I’m not upsetting the neighbors. If I tweak anything from that video clip, it’d be a larger muffler to bring the volume down. From what I’ve read a majority of the rasp can be eliminated further up the exhaust and the muffler is more of a volume control device, but I might not be correct on that. But I promise not to rice this car out and won’t stop until it sounds great lol!
