I'm new here so please take it easy on me. I've got a 1999 wr400 with a FMF power core 4 exhaust and from the reading I get with the db meter device I'm a little to loud to race in the BJEC circuit. What are my options to get below 99db, I don't really want stock but if I have got to then so be it. What about the White Brothers "e" series?

i did a bit of research on this subject before I got my Q. Given the strictness that sounds is enforced with in my riding area, i called the rangers and asked what passed on WRs. Q 99% of the time, the others much less. the bike was uncorked stock when I got it. I got the Q before I got the powerbomb SX. With just the Q I noticed a little loss in power, mostly on top. It was MUCH quieter though. The powerbomb did make a little more power On the bottom, but not so much so that I would spend the funds on another if I had to replace it. Have passed sound, albeit right at the 96 limit, several times now.
