[Rush 335i]

I've trolled through over 150 pages of exhaust mods (golf tee, and 'performance' mod, where you replace the pipes in the back box), looking for a graph showing the operation of the exhaust valve.

It shows when its open or closed, at what rev ranges and what gear. I've tried searching through google too, but just cant find it...

Does anyone have it saved, or know what thread its on? I wish i had saved it when i first saw it! I'm trying to work out what exactly i want to do with my exhaust but i need that info!

Never seen this but I would like to. Will be keeping an eye on this thread

Is this any help? Ignore that it's on the M3 site - the video is for the 335i

I guess you are aware that modifying the exhaust in isolation will have negligible effect

Cheers for that, but not quiet what I'm looking for! what I've seen is actually a graph, showing when the valve is open across engine revs/ gear.

I had done this mod on my e46, by wiring a switch into the cabin, which was fun. But thinking of going in a different direction with this one.

Thanks anyway, will keep on looking!
