Replacement header is a four into one unit, no welding a Y-pipe on to it. Mild steel. Top quality. Includes gasket and lock nuts.
This header is the result of years of fine tuning and actually fits the Jensen Healey. Beware of older headers or used products- they will give you no end of suffering when trying to install.
This replacement unit is great header (the optional parallel merge header is no longer available). I've used it on my JH and found installation much better than previous ones. Highly recommended. Fits all years Jensen Healey. Federal version Jensen GT with catalytic converter requires modification, do not use on GT's that require smog check and original equipment unless you're removing that stuff.
Please note: if you live outside the U.S., we've found that this item can be shipped via the U.S. Postal Service Global Express (3-5 day) to the U.K. and Europe for about $165, or about $195 to Australia. The large size and weight makes this item expensive to ship internationally.
