Exhaust modification
Hello all, had my zed up on the ramp today.
I am having the centre scilencer cut out and a straight pipe made all the way to the back box.
The centre box is reasonably small - same ish size as the back box.
Has anyone had the done. Not expecting any performance gains. But hoping it will be a little throatier. Not night and day but more ommph!
It's a 2.0 2015 btw.
Cheers

Pre or post facelift? You won't gain much noise but you will get better throttle response on a pre facelift car.
Get one of my modified backboxes

its an e89, not many people have fiddled with these it seems. I had a cooper s and a fjcw mini and removed the centre silencer, sound was tremendous. Will see how it sounds, super sprint offer the pipe but at 350 euro c. its a bit pricey!

I literally went to my local power flow place on Tuesday to enquire about this.
They removed a box for me on my old R53 MCS and it was great. For some reason they decided to quote me just shy of £300 to remove the box on my Z4. So I told them to leave it.
Another company has quoted me a touch over £100 and they have an excellent reputation so I may take it there.
I'm worried that the car will become droany.

If the box is completely removed, it WILL drone. When I mod boxes, I ensure that a proportion of the gasses is still routed through the box to ensure there is no drone.SteveSmith wrote: ↑Thu Sep 14, 2017 8:25 pm I literally went to my local power flow place on Tuesday to enquire about this.

I'm considering a little chop to one of the two 35i back boxes. Mainly to enhance that off stroke sound between the two boxes.

Mines a 28i but same engine. From my research I couldn't find anything! I've seen some youtube videos of the supersprint and Eisenmann systems, but you need to hear things in real life to know.

Been tempted on this myself, but may just hold out and change the full system
