[QUOTE="Uechi45, post: 271900, member: 20921"] I have taken exhaust level readings. Here they are. 1. KLX300 with stroker head pipe and Supertrapp IDS2 with 12 discs: All measurements directly behind(unless otherwise noted) Idle@36"=85db 1/4@36"=98db 1/4@72"=96db 1/2@72"=99db Measurements to the sides at 90 degrees were about 1db lower 2. KLX300 with stock head pipe and muffler with baffle removed: Idle@36"=80db 1/4@36"=92db 1/2@72"=94db Wide open @72"=107 3. KLX300 as above but with 1" diameter turn down tip (home made) Idle@36"=76db 1/4@36"=90db 1/2@72"=93db All measurements taken with Radio Shack analog meter "A" weighted. If anyone else has done similar tests please let me know. Also, what are the limits for various events? (enduros, hare scrambles) or just the limits that the Green Police look for. Thanks. [/QUOTE]
