Sorry Chris, a bit late to this...I've been busy!

2013, 7800 miles, been on its current (3rd) bevel box since 1200 miles, steel pulley (Huge Improvement), no NVH (was told at the factory it wasn't worth it!), Morris Lodexol changed regularly, gets noisy on the motorway when warmed up and at lower speeds after a motorway run.

Doesn't seem to be noisy on the race track though...but my Stage 1 exhausts are....101dB on Saturday....was under 90dB a few weeks ago at Loton Park
