Looks like dual resonators, bet it's not too obnoxious, but you'll have to swap out more of the exhaust with the DP being welded come smog time. Not a real big deal. free bump.

I have a helix turbo back and at first I thought it was loud, which it is, but I got used to it after a couple months, I think it is around the 100+ db mark in a spreadsheet I saw.
