Stillen 350Z/G35 Headers

"The long awaited STILLEN 350Z and G35 Coupe and Sedan Headers are now (have been) available. After months of development work, these headers produce big increases in streetable power and torque on both NA and FI 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 @ 6200 RPM and 18.5-lb/ft @ 3800 RPM at the wheels. With STILLEN's 18 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 converters and are available in two versions; 100% Stainless Steel or Ceramic Coated Mild Steel both are manufactured by STILLEN. Check out our new Race Pipes 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. These headers do not remove the cats, but are not 50 state legal, check your state regulations.

C.A.R.B. Pending!"

Don't know too many people that have gotten them.

I do know that Stillen's exhaust supposedly gives the best gains of most exhausts for the Z, but it also weighs more than stock, so the gains are somewhat minimal.

 

The Stillen headers are BORLA headers just renamed.

You will lose HP with them.
