BCS power valve back boxes for z4m

[Bombardino]

BCS power valve back boxes for z4m coupe and roadster. Bought off a member on the z4 forum earlier this year, Although they sound very nice I prefer the intuction noise of the Eventuri I have fitted which was being drowned out by them.

These go on the OEM mounts? Got all the bits needed for installation?
If so I think I'll cancel my Supersprint order and give these a punt.

Dirrect replacement, the only thing needed is an additional bolt which will come with the boxes.

I'll take them, will send pm soon. Can even get them tonight

Sold to Optimum in less than 2 hours can't be bad.

Thanks Bombardino, they look great and I'm looking forward to getting them on the Coupe!

After hours of listening to sound clips & now hearing a few exhausts in person the BCS Powervalve are at top of the list for my Z4M.

I think I read initially Powervalve offered these backboxes in a sport / prestige option but then refined the design to offer one option only?

Obviously missed my chance with Optinium replying first but do you know which design these are?

They currently offer only non-valved on their website for £895 with a choice of trim/tips.........

They were the non-valved version, I don’t think the option of sport & prestige was in production for long.
