Are exhaust bobbins still an issue on the latest M3W's?
The later cars use uprated, universal M8 bobbins. I replaced these after two years while fitting the Stage 1 but they showed no sign of deterioration. If you were to get one of these fail early it would be worth making sure they are not under tension due to poor exhaust alignment as this may also lead to an eventual exhaust failure.
If you plan keeping a spare in your kit it is worth knowing the ones removed had been trimmed at the factory by just under 1/4" on the exhaust side.
