Ive been told that they will pass the 92db idle test with the cats. I have 1100mm of muffler and the 4 inch cats. Unfortunatly I wont know till I front up at MVR and do the test. Iam looking at some marine silencers they use on the speed boats in the US that will drop 4-5db so they will be my back up plan.
