Will the CSL backbox be heavier or lighter than my Milltek, I have to say that CSL backbox looks much bigger!

What kind of weight savings are the headers, x-pipe, mid-pipe and cats over the stock M3 exhaust?

Hello there, the back box is still very substantial so you're better off with the Milltek, as to whether it fits I would suspect it does, as otherwise Milltek would loose out on backbox only sales. Please confirm with them first though.

The manifolds are very light as is the mid section, cats are noticeably lighter but not dramatically so.

I think there is a comparison on one of the M3 forums and somebody weighed the parts.

Thanks
