This is a large bore flex pipe assembly for use with aftermarkets headers.
The inside bore is the same as the Tri Mil and Datsunparts collector bore so the collector length is effectively extended. This results in a better torque curve across all usable RPMs.
After the 2.5" collector extension, this flex tapers to 2" ID to slip over 2" pipe.
Heavy duty galvanized and stainless steel construction.
Includes gasket and fasteners.
As always, a better part at a better price!
Made in the USA.
