, someone here on the forum dissabled this valve and created more engine sound with this[snapback]186597[/snapback]
[/quote]I dissabled the flap on my 330i, it gives the same throaty sound as a sports exhaust. Discnnect the vaccum pipe and plug the pipe with a golf tee. Then listen to the difference. Dont think it effected the performance but it sounded great.

My Ride: 525dA LCI 08, space grey, M-tech, Advantage, Comfort, Nav Pro 8.8, voice, black dakota, seat heating front and back, active steering, comfort access, comfort seats, glasroof, auxiliary heating, head-up, night vision, bluetooth, DVD multimedia package in backseat, satin chrom, auto headlight control, PDC, adaptive headlights, CDC, HIFI, remaped 240hp 500nm
I have seen that the cars with bigger motors have exhaust pipes with larger diameter. I have an 525d which I really want some bigger pipes. 
Does anyone have done any modification like this? Any pics and DIY? I dont necessery need a complete exhaust set, but just the estetic.

Is quite normal for cars with bigger engine have bigger pipe because they simply produce more exhaust gas.

[/quote]A golf tee is what you put a golf ball on before the initial drive down the fairway or were you joking? I personally use one to launch balls into the hedge.
I've followed my own car at slow speed and seen the flap moving so I assume its purely a noise retarder.

[/quote]Yeah but if it would look better overall they would have put it on all e60 models don't you think?
Finaly i think it has to do smth with the volume of the exhaust gases. If they fit a big exhaust (pipes and finals) to a 520i let's say...yeah you would get a bonus in the look factor but i think you would also get a drawback in the performance. If the engine doesn't push out that much gas, the gas would stick around more to exit the exhaust resulting in a bigger and unwanted backpressure wich leads in less perofromance.
I don't know if i explained it the right way.
Anyway...i'll try to find out more about that flip cap.

This was really nice pipes (tips) - This is what I'm looking for. Are they original or have you changed the exhaust system? Can this be done with only changing or adding the tips?
