Depends on the resonator and how it works with the rest of the exhaust.
From my other thread I linked:
Stock exhaust + Apexi header/front pipe: 85.7db
Blitz VS/VSR (quiet exhaust) + Apexi header/front pipe: 84.6db
Same setup w/ Tomei 60R: 106.6db
Same setup w/ Blitz F-Ti (full Titanium one piece exhaust): 102.6db
Ultimately the header isn't as key in sound suppression as the front pipe. The Apex'i header is a 4-2-1 catless design.
