Ok, so I ordered the lower DB baffle inserts and they made a HUGE difference. It still sounds beefy as before but it’s moderately less loud.
Put it this way I am the rider who always wears earplugs, even in a shoei helmet. Wind noise is too much for me at anything over 45 with no front wind screen. I had to put my ear plugs in all the way to keep from headaches with the cobra 6003's I did. BUT now that I put in the 9027 baffles (new style) it’s about 5 DB lower overall and I can ride with no ear plugs like the stock exhaust was before but it still sounds awesome, and best of all, NO DRONE!
I have a decent DB meter and I measured the OEM exhaust at 66 to 68db at idle standing behind and 74 to 76 db at 5500 RPMS
The Cobra's with the cat removed, and the box modified, I was at 75 to 78 DB at idle and 82 to 86 Db at 5500 rpms
With the 1-5/8 baffles installed it measured 68 to 72 at idle and 76 to 79 at 5,500 rpms.
Remember decibels are 2x the volume per 10db.
I am SUPER happy with the results.
