Ive got a DSP Full system and its WAY loud well over my Old YZ250 witch got tested at over 109db. Im looking to get a new full system, my question is what pipes do you guys have and do you like them? Im looking for something fairly current so I can buy a quiet core (purely for the Oregon dunes ), and some other tips and stuff. Def needs to have a spark arrestor. Im not prejudice of any companies FYI I like Dr. D, simply because I met doug about 5 years ago and he was a quality guy! Thanks in advance guys!
