Anybody ever fabricated a muffler for an e34 ?

[Derek A.]

I know thew way the muffler is shaped on these cars is pretty goofy. Has anyone ever make something using aftermarket pieces ? I had an exhuast made up for my e28 car - but that was a different layout than e34. Any ideas ?

flowmaster? those are real heavy and weldable too, dont know if any are small enough to fit in the hole though.

every non factory type muffler i've seen on a e32/34 has looked/sounded like ****, my answer to cheep larger pipe was to adapt a e32 750il catback, it fits and sounds good, nice deep sound. i posted a few pics for someone else, http://www.bimmer.info/forum/showthread.php?t=8653&highlight=playero

my 535 when i got it had a flowbastard where the cat was supposed to be and a glasspack where the muffler was supposed to be, it was real shitty sounding, not just loud but loud and bad

so you think straight pipes are outta the question?

damn near went deaf test driving a goober friend of the boss's e30 325ic with nothing but two cherry bombs side by side in the back (one for 3 cylinders) i put a short shifter in it and needed to rap it up a little to see if it worked good and with no ac and the windows down had my left ear ringing. i told that douche when he drove it by the shop to show off his new "performance" exhaust it's too ****ing loud and would get old in a week and miserable in two, in two weeks it was quieter :D it sounds cute at first but that wears off

I've read a few exhaust design articles and the difference between having a straight through pipe or a resonator is a factor in what causes the annoying coffee can sounding muffler. Straight through piping is better for say racing purposes but can cause the coffee can syndrome. Also the glass pack/pipe (fiberglass packed) resonator will do the same overtime. The fiberglass is heated and work hardens over time and will give the rattling coffee can sound also.

I love the way Winfred writes. really

I did my own 3" system using 2 resonators, 1 cat, and a Gibson muffler with dual tips. Originally I had just the Gibson and the cat, and it was disgustingly loud. So I added one resonator, and it helped, but the second one was what finally made it driveable. It doesn't sound like a rice rocket either, there's more rumble than anything else, but it's still slightly too loud, so in the spring I may redo it in stainless using a different muffler/resonator setup. I don't get any weird looks from other drivers or pedestrians, so I guess it's not THAT loud now :)

Allan any pictures? The price of replacement mufflers and CATs, unless you go OEM is off the charts. If you are not drawing any stares you are doing good. I would like to do a similar system maybe using Borla mufflers and Magne Flow CATS instead. A good spring project or until I can no longer put up with a rattle that just begin to show up when I stop at a light.

I've seen a Flo master on a 535i. Very odd looking, as it was actually mounted on it's side and the exhaust tips were twisted about to end up side by side instead of on top of each other.
Local guy has a custom 3" set up for his turbo '89 525 that I believe uses a cat, no resonators, and a muffler. I'll double check.
