If you buy the Long TORS don't modify them unless you want noise...
On my 07 sm I bought a short set, at 6k miles they weren't quite grumbling enough. being as i am, I set about a minor mod and now... On your scale they are about 11. our db meter tops at 130,
I can't get a reading at tickover... But they do sound beautiful and the local HOG know me from a mile away...
