Stillen 508350M Mild Steel Header 03-07 Infiniti G35
The STILLEN 350Z and G35 Coupe and Sedan Headers are the finest available. With months invested in development work, these headers produce big increases in streetable power and torque on both naturally aspirated and forced induction vehicles.
The equal length design of the headers allows better and more efficient exhaust scavenging which contributes to the performance gains tested on the dyno, 11.5 hp at @ 6200 RPM and 18.5-lb.ft @ 3800 RPM at the wheels.
With STILLEN's 20 years of experience in designing and manufacturing Nissan performance parts, you should have complete confidence that every STILLEN product is of the highest quality and has under gone extensive research and development before production.
These hand crafted shorty headers do not require the removal of the catalytic converters and are available in two versions; 100% Stainless Steel or Ceramic Coated Mild Steel and both are manufactured by STILLEN. This part # is for the Ceramic Coated Mild Steel Headers.
Installation should be done by a qualified mechanic with proper tools and a lift. This is not a backyard bolt on. For the Stainless Steel Headers see part #508350S. These headers do not remove the cats, but are not 50 state legal, check your area's regulations. Complete the performance upgrade with STILLEN's new race pipe (#503435).
