## Description

High flow catalytic converters that will pass emissions testing for 350Z 07-08, 370Z, G35 07+ Sedan, and G37. *New and Improved with more installation clearance and long term strength! The factory catalytic converters are well known as the biggest "choke point" in the factory exhaust system. These high flow stainless spun catalytic converters blow away the stock converter flow rates while still maintaining legal emissions levels. Constructed with stainless tubing and 3/8" stainless flanges (converters are aluminized steel). Fully TIG welded and true mandrel bends used throughout. These converters will bolt up to any header (factory or aftermarket) and any exhaust (factory or aftermarket). These pipes also retain the factory Oxygen sensor location and WILL NOT THROW A CHECK ENGINE LIGHT!!. Expect great performance gains from these converters as they have dyno'd between 7-9 hp at the wheels on factory 370Zs. They only add a slightly more aggressive exhaust note and do not have the pesky "raspiness" between 3-4k rpm that is seen with straight through test pipes. All of our pipes come complete with bolts, washers, and lock nuts. ** Please check local laws regarding catalytic converters. These pipes have passed visuals and sniffer tests in CA (the strictest state on emissions) but they do not have a CARB number associated with them. **
