Dundon 981 Race Headers provide substantial gains in torque and horsepower throughout the rev range. They are a race system so are for track or off-road use.

All Dundon headers are made with 321SS, the advantages of this are numerous and include, better fitment, higher heat tolerance, superior resistance to exhaust gas corrosion and a lifetime structural warranty to the original purchaser. 

The headers attach to the factory PSE muffler and are quiet with no drone at cruise, but put your foot down and they're all kinds of flat six glory.

Dundon Headers are specifically designed for each vehicle and engine.  Unlike our competition that uses a one size fits all, we tailor each system to the unique needs of each engine.
