I sold my 426 to my brother and he took it out this weekend for the first time. I installed a FMF Q about a year ago and never had a problem. He went riding at Rohwer flats(California) a Ranger stoppped him and gave the old spark arrestor test by using a poker. My brother said the guy tried about 20 times and finally got his poker to pass through the spark arrestor. My brother told him to try it again and after 20 tries he got it to pass through again. I spent over $300.00 on this pipe tring to do the right thing with noise and spark and my brother is now getting fined. Has anyone else had this problem with the FMF Q? The ranger was on a bike I guess he is an AS.....!!!!!!!! Any feed back would be great. thanks!
