Sup guys, I know theirs plenty of reviews on the old DRD models but I wanted to see if any one yall had some reviews on the new ns4 model. I have a '14 yfz-r and I orded the pipe after searching thru slip ons, I know the " go get a full comment is coming" but for what I do a slip on is plenty and having the option to order the header will do me fine. Anyhow guys just wanted some solid info on the new DRD slip ons. I know they re-did the packing for a roll type and upgraded some hardware. I appreciate it!
