I did this mod yesterday and drove down to a BMW Dealers my Sis works at to get my Oil Service and Front Bushes done...

I couldnt believe the sound difference from the exhaust, i had the stereo off the whole way and couldnt help grinning!!

Coupled with the oil service and fresh bushes, the drive on the way back was amazing to drive and amazing to listen to!!!!

Going to have a look at this tonight.

I'm actually quite excited... Hope it IS rusted shut as I'll be dissapointed if it's working fine or stuck open!

Always thought mine was stuck open, but then realised it stays in the open position when the car is off. Disconnected the hose last night and wow what a difference! You can hear the difference at lower revs especially if your cruising in 5th and blip the throttle. Has a nice deep boom to it now.

Very happy!

wow just done this, how cool is it to cruise round at low revs with that 6 cyl burble! loving it!

Mine was stuck shut - used some WD and a pair of long nosed pliers and happy days!

Will it have been restricting power with it being stuck shut?

I smashed the living hell out of my completley stuck valve on the weekend and finally broke it off. (Turning it didnt work, it just bent the metal as it was so stuck).

When i first took it out for a spin i didnt notice any difference but when it had heated it up you really could, sounded Ace.

Doubt you'll feel a difference. But you'll definitely hear a difference! My cars had it done and it sounds so nice at around 2k revs. Purrs nicely.
