Well packed with super quick delivery as always. An easy fit to my MR230 which sounds much better. Only downside is I wish I'd done it sooner.

Delivery was super quick and arrived well packed, fitted this part as a prevention as the symposer was still in good condition. Plus added to the rest of the mountune parts already on my mr375. Thanks again.

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.
