From the Stillen web site
STILLEN HEADER 03-04 350Z & G35, CERAMIC COATED M/S $811.00
STILLEN HEADER, 03-04 350Z & G35, STAINLESS STEEL $998.00

The long awaited STILLEN 350Z and G35 Coupe and Sedan Headers are now available. After months of 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 ft-lb @ 3800 RPM at the wheels. With STILLEN's 17 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 design before production. These hand crafted shorty headers do not require the removal of the catalytic convertors and are available in two versions; 100% Stainless Steel or Ceramic Coated Mild Steell both are Manufactured by STILLEN. This part # is 100% Stainless Steel Headers. Stay tuned for STILLEN's soon to be released Race Pipe for the 350Z and G35 that mates up to the header to make a perfect combo of fit and performance. Installation should be done by a qualified mechanic with proper tools and a lift. This is not a backyard bolt on. For the Mild Steel Ceramic coated headers see part # 508350M. These headers do not remove the cats, but are not 50 state legal, check your area's regulations.
