Competition ZTek Porsche 964 Mandrel Bent Bolt-on Race F1 High Velocity Headers. Fits ALL 1989-1994 Porsche 964 cars only. ZTek Headers are made from the strongest 14 AWG Fully Mirror Polished SHOW-QUALITY Stainless Steel, but fully CNC lightened to only 6 lbs!! The LIGHTEST 964 header system we have tested. ZTek Headers feature the best forged SS F1 merge collectors and super strong TIG Welds for efficient exhaust gas scavenging, which add to a warm idle and slightly more robust WOT note. Customers dyno's have seen increase 11.4hp and 12.7 ft/lb torque on stock 964, with just the header swap. Although on a stock car they work great to increase horsepower and torque through the entire power band, it is HIGHLY recommended to pair these headers with a ZTek Super Sport Muffler for even more significant gains in power and great sports car sound. All ZTek exhaust components parts come with a 100% MONEY BACK 10day/100mile Guarantee! We'll let you install it, use it for 10days/100miles, whichever comes first, and for any reason if you are unsatisfied just send it back for a 100% refund of your purchase price. On top of that we also offer, an industry leading limited LIFETIME WARRENTY on all ZTek exhaust components for as long as you own your vehicle.
