Product Details 1320 Performance Mini ramhorn header / turbo manifold 2.0 version for the Polaris Slingshot is design upon our version 1 header the version 2 header have the same feature as version 1 but can be either used as a header or turbo manifold Many customer ask what is the difference between the version 1 and version 2. well the short answer is the version two is much stronger. we use thicker stainless steel tubing on the version 2 and 316 filler rods on the SS to SS welds. version 2 is for customer that have an aftermarket exhaust system on the slingshot and some of those exhaust system have no hanger or poorly design hanger that put alot of stress on the header and another reason why we made the version 2 is many people going turbo on the stock manifold our header are so well build they will with stand the duty of a turbo manifold up to 350hp. The stock cast manifold is not only ugly heavy but are a huge performance choke point due to tiny exhaust ports and flange ports. stock manifold collector size is only 1.742 inches our collector is true 2.5 inches *Extra thick stainless steel to handle more heat and stress *Tig welded in and out for durability*ported runner and collector for extra smooth flow and most hp gain *True 2.5″ collector*Precision laser cut flanges *OEM fitment can be used with stock exhaust and aftermarket exhaust system*Dual o2 sensor bung on header. Extra o2 sensor bung can be used or wide-band or other tuning oxygen sensor. Plug included if not used. *California law generally prohibits the sale and installation of aftermarket exhaust products UNLESS such products are installed on vehicles that did not come originally equipped with catalytic converters or are used only for racing and are never used upon a California highway.
