1992 325i Exhaust

[M3wannabe2004]

I'm not sure if im imagining things or whether it's cos i was used to my 318 but.. the exhaust on my car does sound quite loud even though it's new. Am i right in saying that nothing other than the back box can cause the car to sound loud?or can other elements of the exhaust system effect it?

But its ugly, and it smells bad, but damn, it sounds great!

i'm having the same problem with my 1995 325, this must be pretty dang common. that sux tho, so you have to replace the cat.? is it possible to maybe just patch the hole on the cat. instead cause they cost a crap load, atleast patch it so its quiet and i'll probably replace them in the next year or two.

anyone?

I like how mines sounds, it sounds good, lots better than those angry lawnmower Honda exhausts (not saying anything against Honda's, I love them too) but an exhaust that sounds like that when you're going...10 mph? Mines is just sexy, even with the gaseous smell =D.

well this is how mine sounds...

plz have lotion and tissue ready...

Well, here is the reason why (non-Vanos E36) 325i's are louder than later Vanos equipped cars; the addition of Vanos Intake system somehow quiets the exhaust through the intake or valve timing changes.

Everyone has heard the difference in an engine after a cam swap to a hotter cam (I hope) and the non-Vanos cams are more aggressive then the Vanos cams because they do not have variable timing to artificially increase their breathing.

Now, you may still need to fix your exhaust, but there are more than a few similar threads that mention the non-Vanos aspect as the reason, if you would like to search them out.

I pretty sure my muffler is totally gone, considering I keep finding chunks of baffle in the tips.

same exact problem with my 93 325is, cancerous rust holes in the exhaust. but it sounds very deep and loud, though its probably robbing some power. im about to find a cheap oem m3 catback and put it on there until i can save up for a borla or a supersprint.
