Catted Downpipe
Factory F-150 downpipes are very restrictive because Ford reduces the diameter of their primary cats from 5.5″ to 5″.
Built for the F-150
Our turbo flanges are CNC laser cut 1/2″ 304ss flanges and we TIG & MIG weld the downpipes for strength and durability.

With SPD Alpha ultra high flow cats and larger 3″ diameter mandrel bent tubing, you will improve throttle response, mileage and overall performance while reducing turbo lag and exhaust temperatures.
They are extra loaded with Rhodium, which is a platinum based alloy that is required in a catalytic convertor to reduce NOX in the exhaust to meet the new emission standards. SPD Alpha Cats SPD Alpha Cats are next generation ultra high flow green emissions catalytic convertors and are truly an industry first.
