These 350Z G35 G37 High Flow Cats replace your factory catalytic converters, letting all the exhaust pass through freely, but not the noise. This gives an equal amount of flow, but without the raspiness. The exhaust note will only be slightly louder then stock, and have a slightly deeper tone.

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). They also retain the factory converter brace brackets and include all necessary hardware. These pipes also retain the factory Oxygen sensor location and will not throw check engine light.

Expect great performance gains from these converters as they have dyno"d between 4-10 hp at the wheels on factory 350Zs. 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. **
