I agree with BHolland. The whole Brock Davidson system weighs about as much as just the Holeshot header. I'm not a drag racer, but the throttle response with the Hindle was much smoother. I did have the older Holeshot system so I'm sure the new comp is better. Also the Brock Davidson (STREET SMART SYSTEM), the header is stainless and the can is titanium. I don't think there is a lighter system with more ground clearance out there. Although some might have more bling. Oh I forgot, it sounds great.
