Does anyone have decibel readings for each catback with LTs and catted Y, I am sure now set on buying some ARH's with a catted Y, but not sure which catback to get. There is a harsh noise restriction in Pitt Meadows for autoxing cars, which is 95 db.

So I would like to know if anyone has decibel readings for ARH LTs with a catted Y and the following catbacks:
-Magnaflow
-GMMG
-TSP rumbler
-Borla adjustable
-And any other catbacks that have good flow.

There is a list, maybe located in a sticky, that has decibel readings for like the top 15 catbacks. You have to search around for it.

well after running the gmmg, kooks lts metallic cats that setup was way over 95db....I also remember that someone took a video of a corsa exhaust with lts and cats and it db'd around 95db on a a cold start.

There is a list around but my old Random Tech catback was 90db on startup cold and the stainless works catback I have now tested at 102db on cold startup. 3-1/2" exhaust. No cats, H/C/I.
