alright, well, this wasnt built for a VF 700 F, but it was on a V45 sabre, its pretty much a full system utilizing the stock rear header pipes, and its own front ones. now, I'm not super certain what brand the system even IS, I think its a Mac, but cant be 100%, since I cant find any markings. its not bad though. I'm also playing with a projector I want to make into a headlight all its own, ideally two so I have hi/lo beam, and can utilize HID lighting properly. this is a rough mockup so far, maybe if I can do an over/under, I'll go for it, or side by side. I'm undecided yet. so tell me what you guys think. and yes iknow my signals are kinda funny lookin.
Unfortunately, that header won't fit your F as it is now. The Saber and Magna's front cylinders are tilted downward, quite a bit more than the F's. This means that the front pipes on the header are too short too reach the heads. You could. however, fab up some extensions to solve that. The only other thing that concerns me is the rear bends. I've seen quite a few headers for the F's and they all have a tight radius for the rear pipes before the collector. These look rather long. I'm thinking the Magna's/Saber's have an entirely different oil pan setup to allow these to be longer. You might be porked on this one. Hopefully someone can confirm.
D'OH! oh well, worst come to worst, its a solid beginning and I can have a welding shop extend the pipes, and/or create a similar arrangement accordingly.
