By pass pipe size?

[Rickster93]

I’m after some by-pass pipes for my z4m coupe. I just need to know what size I need. Apparently you can get two different sizes?

Most people have gone for 3/4" for the ///M.

Are you ordering? I'm sure we can get 6 people interested in the other thread.

Does anyone have a link to them and a vid of how it sounds ?

He said he wasn’t sure if he had any of a certain pipe in stock? But I’m up for what ever mate

Apparently they come in 2 different lengths either 360mm or 410mm? How stressful any ideas?

410mm for the ///M.

I think there is more rasp at high RPM, but people have also reported that it's more bassy when idling.
