i have one and i put a glass pack on it if its loud u want it is what ull get and it sounds good also but make sure u get it away from the gas tank i weld some pices on the end of the glass pack and made so i could take off and on as i pleased and i used the stock springs and some how it moved and got on the heat sheld and melted the heat sheld to the gas tank now im thinking i need flex pipe to make it look like the stock one i thought it was better than spending 4 or 5 hundred on some brand name untill that happen the glass pack was olny 40 bucks i think its just as good as any thing elce well hoped that helped and have u had a lot of problems with urs
