FS: Modded OEM back box for Z4M

Danza

Member
I have a pair of OEM rear backboxes for sale that have had the internal straight pipe mod fitted. Substantially louder than stock with lots of crackling and some outright bangs (more than my decatted e36 328 with akrapovic pipes) and a proper WHAP when blipping on downshifts :driving:

I don't have any videos online but if you're interested drop me your number and I can whatsapp some to you

Collection preferred as they're pretty unwieldy (will fit in the boot of a z4mr though). I'm based in whitechapel/twickenham.

£300

Surely you can't have just one :?

No reason why not, have thought about swapping just one of mine at a time in case combined with the GruppeM 2 is too much.

Might that not result in 3 cylinders getting more exhaust flow than the others?

Dan, I've changed my mind on the car, but going through house buy at the moment. If these are still here by roughly August, I'll take them. Can't be seen to be buying car bits at the mo, having kept hold of it by the skin of my teeth!
