Complete set! High flow catalytic converters that will pass emissions testing for 350Z and G35 (2dr and 4 dr)

*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 CARSOUND/MAGNAFLOW 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. The CARSOUND converters are widely known as some of the best and are also marketed under the MAGNAFLOW brand name. These converters will bolt up to any header (factory or aftermarket) and any exhaust (factory or aftermarket).

Expect great performance gains from these converters as they have dyno'd between 5-8 hp at the wheels on factory 350Z's. 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. **
