It makes no difference above 2500-3000 RPMs. It also makes no difference at idle. Below, the resonance is rather loud and obvious. If there's NO noise change at all, then your valve probably wasn't working in the first place.paul330ci said:I removed the vacuum hose from the back pressure valve in the exhaust.
The sound did not increase hardly at all. My car was already fairly gurgly.
Some here were complaining that it was sooo loud. Not sure if this mod really makes any difference.
Heh, I think the problem is that these people who don't hear the difference are just partially deaf.Nick325xiT 5spd said:

People like yourself who don't know sarcasm when it smacks them across the ass is why I'm ... well, sarcastic, I suppose.paul330ci said:Replies by webguy is why I hate asking questions or providing answers.
It was just a comment for pete's sake. I hate these Johnny come lately BMW owners.
How about this: instead of posting an entirely new thread about a topic already covered by 70+ rants in a previously-established thread, just go to said thread and post your comments there (especially when they don't even deviate from anything anyone else said). That way you'll fall in line with all of the other boisterous ranters and you won't get singled out by the big bad exhaust-valve-disengaging webguy.paul330ci said:That is exactly what I mean. Oh well.
