Thanks for clicking over to consider some of the decisions you may face when purchasing your HKS 700-E.

• Exhaust Systems and components:  Undoubtedly, the best bet are any of the stock HKS systems. They are constructed with the same surgical quality as the 700-E engine and they are QUIET! If it is impractical to contain any of the stock systems within a particular installation custom systems are an alternative. The basic rules for the HKS 700 E: Run two into one, rather than individual stacks or mufflers; Avoid extreme tailpipe length or restrictive exits. Stainless Steel vs Mild Steel is much a matter of preference. We like mild steel, especially for prototyping. Ceramic coating the finished product enhances appearance, protects from corrosion, and insulates heat. Green Sky has welded seam 1 1/4" U-bends and other components available upon request. Prices on factory systems are in the mid $500 range. Flanges and basic components to build a system from scratch will run about $100. In the prototyping of our Kitfox installation, below, we approached the project with a thought of producing a system that compliments part, or all of a unified mounting system for manufacturers or individual builders. The following images may help you decide on the options for your HKS 700-E

Here are some images of custom exhaust components we have fabricated to compliment our HKS Kitfox conversion. Raw materials consist of HKS SS flanges, a variety of diameters of U- bends, and a generic industrial muffler. The motor mount and exhaust  system are the heart of our unified power package available from Green Sky Adventures, Inc. Pictured here, the exhaust system is almost ready for Ceramic Coating, which insulates heat and resists corrosion. Green Sky can quote the package in various forms from tack welded basic components to a turn key installation.	An individual builder can fabricate a custom installation from  basic Green Sky components, saving time and money.
	With a little effort, the basic shapes at left and below can be blended into an exhaust system that fits the mission. Slips joints mitigate effects of expansion and contraction.
	A ball joint type connection at left was ruled out on this occasion in favor of a larger tubing diameter sweep, joining the two legs of this collector and shortening up the turn.
