Tips for lowering dB? (Tomei expreme Ti)

I notice a difference in DB with my Z1 headers and F.I. RTP's compared to F.I.'s headers to F.I. exhaust if that helps. Both exhausts are F.I. 12" carbon fiber.

I actually got black flagged and kicked off the track for exceeding db level. Under power I was well beneath the limit but when I would up shift the car backfires under load and it sent the decibel meter through the roof...121 lol!
