Exhaust Cutout

Post by j4jack » Thu 20 Jul, 2017 19:12

Hi All,

So I've been considering an exhaust upgrade but they are pricey! If this goes wrong on me :head: i'll just order a custom X pipe as discussed in the thread below :lol:

I found a thread on another forum about an electronic exhaust cutout, and it got me really interested, here is the link:


So I've ordered the thing, question is how on earth do I go about wiring it it...Its the Z4M roadster that I have, and the battery is in the boot/trunk so should be easy - just want to make sure I don't drill through the petrol tank or any cables...

Wiring advise please!
