Been waiting for this to come back in stock for some time and ordered straight away when it did. The item arrived super quickly from Mountune. It is a very well designed item and great detail with them M logo machined into the top. Fitting was relatively straight forward with the correct tools. Longe reach hose clip pliers are a must in my opinion. Had a bit of difficulty breaking the seal to remove the Symposer hose from the boost pipe but a bit of persuasion with a flat head screwdriver did the job. I refitted using Jubilee clips for added security. Once all fitted up the cabin is notably quieter without the engine noise being pumped in. My car is running MR375 with X4 induction and the car sounds much more natural. Worth noting that the small Allen key screws are 4.5mm from memory and I had to use an imperial tool to screw in tightly enough, there's no need for PTFE tape either. When I took the removed symposer unit apart there were no splits but this is a worthwhile modification either way.

So I recently purchased the symposer delete for my fez st at Ford Power Live. As usual the staff where friendly and helpful. A good piece of kit well made and easy to fit (even for someone like me, with no mechanical no how), had it fitted within 20 minutes.

Installed the symposer delete with the boost pipe upgrade. For me personally this is amazing, it’s removed a large amount of the unnecessary internal noise and allows the natural engine/exhaust tone to be heard. Is a little tricky to install mainly in removing all the OE kit. Once OE is out of the way the symposer is simple to fit. Especially when installing with a boost pipe upgrade as you can install it to the silicone hoses and mount all at once
