I have a quick question for you guys. I'm looking at gettign a Curtis Sparks full kit for my 250EX. I was looking around and I noticed it has an option of buying it with or without the quiet core and spark arrestor. If i bought the pipe with these in, will I be able to take them out or are they built into the pipe? The reason I ask is I do some trail riding and I don't want to get a pipe that's so loud that I'll get in trouble. Thanks in advance!

 

Someone? Anyone? I would imagine someone on here has some insight about this...
