100DB Track Limit
A new local track requires the noise level to be under 100DB directly behind the car at and 95DB on some corners but with a bit distance. I currently have FI LTH and CBE with 18" resonator but it's still too loud, any idea on how to quiet it down without sacrificing power? I also have the side pipe welded to the muffler to reduce the drone at about 3k rpm, but that doesn't really do much at high rev. Thanks in advance.
