Hi All,

I was in a rush and replaced a generic exhaust clamp I installed a while back when I did a rear subframe swap and installed an original E90 330D exhaust clamp but I rushed installing it and today after pulling away slightly quick at a roundabout the exhaust come away just after the flex pipe it literally is about as straight piped as you could get.. But i have to say it sounds like a beast is there any reason to fix this sooner rather than later?

Probably best to just reattach the exhaust. Or did you lose the clamp when the exhaust fell off. I think my immediate concern would be the exhaust fumes getting into the cabin. Not too good for you or your passengers.

it might gas you, i drove a mk4 golf diesel with a broken exhaust for a few days and was ok when driving but you could smell the fumes when stationary or in slow traffic.

It won’t damage the car short term if that’s what your asking

[nomiS330d]

I don’t know if it will cause any damage but I doubt it. I started mine after I’d installed its diff but before refitting the exhaust, sounded quite good (for a diesel), I was surprised how relatively quiet it was but I didn’t drive it. Got me wondering what that massive rear silencer actually does!

Shit me, today I had to crank the car twice because ive got a parasitic draw from somewhere and I had my windows down and when it started a big cloud of smoke blew I'm through the windows and I vacuated the car

Won't stay like it for much longer but I will miss the extra turbo noises and deep sound lol

Yeah, on mine it's a much deeper sound and you can feel it through your feet, on WOT it's absolutely crazy, it sounds like a raspy petrol engine, not sure if I like the top end sound but I love the lower rpm sound.

Yeah won’t do any damage, engine does require some back pressure though but you’ll be ok��

It sound so nice as well! Took a while to get used to but the spool is louder, and if you come off the accelerator just as the gear changes it has a deep growl sound (not the most accurate description) and on WOT it's really raspy, it's like a Genuine BMW straight pipe
