Howdi,
I bought these decat pipes, fitted them, ran them for a few weeks, but they caused a flat spot between 3k and 4k rpm in my Z4 M.
https://www.dcperformance.co.uk/cheap/357912/BMW/supersprint-front-exhaust/sp789812.html
I am selling them in the hope someone else has better luck.
My Z4 M is modded in the following ways:
The reason I bought these was others in the forum run them and do not have any flat spots. A few forum members contacted me when I was having the issues with their experiences and no-one could understand why the flat spot was there. I imagine the combination of mods I have are not compatible with them in some way but I am in no way an expert.
If someone fancies a go at making them work in their car then now is the chance.
£275 collected or plus delivery.
Cheers,
Phil
