Fitted mine yesterday. 30 min job……the cut was awkward but everything else was easy.
First observation was that though it’s only 10mm larger in diameter it fills the diffuser so much better. It was also perfectly aligned without any adjustments.
Fired it up and immediately the difference was night n day. Much more meatier. After a full test run it sounds awesome, lots more crackles pops n bangs at much lower revs in sport mode. I’m very impressed with fit, quality and sound.
