These ZTek Porsche 996 Sport Cats are direct replacements for those restrictive stock cats and feature 100 cell German Metallic cores, half of stock=twice the flow, lowering backpressure, increasing useable power, and lowering exhaust gas temperatures. Adding ZTek Sport Cats to any Porsche will lead to a slightly stronger idle sound, and much nicer sounding WOT note, giving your 996 a meaner growl during acceleration but keeping your exhaust note mild during highway crusing. All tubing is made from very strong but light T304 Stainless Steel polished to a mirror shine and all bends are CNC mandrel bent for maxiumum flow. Flanges are lazer cut and then CNC machined, and port matched for a perfect fit. These Sport Cats utilize all stock o2 sensor locations for maximum performance and reliability. Customer's dyno results prove increases of 10.3 hp and 11.5 ft/lbs torque on a stock 996, with just the Cat 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 Sport Cats with ZTek Headers and Mufflers for more significant gains in power and an even more unique sports car sound.
