I have had some crazy problems with my Dasa Exhaust. I think someone started to build it on friday afternoon, and finished it on monday morning. After talking to FUELATV this is the first ever pipe that they had sold that had any issues. All I can say is they have bent over backwards to get my problem resolved. If anybody is worried about buying from someone over the internet instede of local? Take it from me these people recieve an A+ in customer service and satifaction after the sale. I am glad they are a part of KFX450Central.
