XBCrew proudly brings you affordable Scion XB high performance stainless steel exhaust headers. After market headers performance is much better than your OEM exhaust manifolds for a number of reasons. Today's XB OEM headers must meet all EPA and DOT requirements and standards by law. The standards they need to meet are noise abatement and Mileage requirements. And  in doing so they tend to be very restrictive with baffles and tight bends that causes excessive back pressure which  kills horse power and torque. The manufacturing progresses in its self  does not help with mismatched connections and very tight radius bends for clearance and cost demands placed on them by the manufacturer.

XBCrew's custom XB headers meet all these problems head on. Starting with our headers mandrel bent stainless steel tubing that insure the best possible flow characteristics possiblefor your XB to minimize turbulence and back pressure while taking advantage of the inertial scavenging effect. Scavenging is the effect of inertia within your XB headers. It works like this, as the exhaust gases exit your heads and continue through the XBCrew headers it is in motion and this motion literally pulls the gases out of your head aiding in the extraction of the spent hot gases, This inertial scavenging also helps pull fresh air/fuel mixture into the combustion chamber as well. This effect also helps to increase your XB low RPM torque. This is where the mandrel bent headers tubing comes in too with smoother high radius bends and matched couplings that facilitate the headers performance with less restriction and lower turbulence making for a high performance XB exhaust system. Our XBCrew performance XB exhaust headers coupled with our XB cat back and axle back system can produce up to 30 more horse power with a substantial increase in your XB torque also. Together the XB headers and exhaust system will impress your friends and put you ahead of the competition.
