Empi's new premium extractors are made from 1 3/8" 16 gauge steel with extra thick flanges. Tubes are mandrel bent to insure smooth exhaust gas flow. All flanges are surface ground to ensure a flat sealing surface & finish ground on I.D.'s.
This flanged version requires your heater boxes or j-tubes be flanged (you'll love not having to mess with those clamps again). The 3 bolt muffler flange is at the 1:00 position & will accept a wide variety of mufflers and stingers.
Comes with high quality gaskets, stainless steel bolts and copper nuts to resist corrosion. This model is ceramic coated. Fits bug type engines.
Allow 4 days to ship, please.

Empi says that you should warm up and then allow a cool down period on any ceramic coating to "season" the ceramic prior to reaching any high rpm/temps. Otherwise some blemishing may occur.
of these to my order now.
