Just had an oem exhaust put on my 93 325i. The tech said it would be a little loud for about 2 weeks while the carbon had to build up in the muffler. It's been 1 week and I get this droning when I'm going 30mph and the rpms are between 1500 and 2000. Has anyone heard of this carbon build-up period? Can I get rid of the droning by adding a special exhaust tip or something? As you can guess, I prefer a quiet exhaust. Thanks!

Exhaust tips are generally designed to make the exhaust note louder. I would just be patient and give it time. If you listen too hard, you will deffinately hear somehting. It's a BMW :P But seriously, if it's oem, it will be fine.

'Preciate it. My neighbor has a 325xi that seems very quiet and I was kind of wondering why I couldn't achieve that same level.

not sure...she's had it for a while now, so maybe 2000 or 2001...are you thinking that there's something special about that model?

Man my UUC drone alittle bit at low rpms 2k and below. I'd like it to be quieter but then again what is more annoying to me?....the aggressive exhaust or the SQUEAKY lil things I hear from the rubbing leather seats and suspension. I rather stick with my exhaust since I know were it comming from. Oh yeah give yourself more time usually 1wk to 3wks for break in. r u sure its oem? I also had a m3 exhaust on my 325is.....tooo quiet. :lol:

It's definitely stock. Is oem and stock the same thing? I had it installed at Meineke because the baffle was completely gone in my old one, and that was much louder than the current one, and Meineke charges way less for labor than the dealership, and they're open on weekends.

I listened very closely to the e46 next door and it actually sounded a bit louder than I thought coasting around our parking area. Either way, I'm probably being too picky. I also get the squeaks from the leather seats rubbing against the center armrest and remedied that by simply not lowering the armrest.
