350z DE Z33 Kinetix Racing Resonated Test Pipe

So we now offer a full stainless straight through converter replacement, but with a stainless exhaust resonator welded in-line. This gives an equal amount of flow, but without the raspiness. The exhaust note will only be slightly louder, and have a slightly deeper tone.

Catalytic converters are the biggest "choke" point in the exhaust. These pipes have shown a 5-10hp increase at the wheels on factory 350z's. Our CARB legal converters will show almost equal gains, but straight throughs are a MUST for any FI application. On Turbocharged cars (example Greddy) we consistently see gains of 25-35 hp !! with faster spool times.

Constructed entirely of S.S. and feature true mandrel bends and 3/8" thick flanges with a highly polished 4" body full stainless resonator on each pipe. They also feature factory located O2 oxygen sensor bungs so factory sensors are retained. These will NOT THROW A CHECK ENGINE LIGHT after installation. They will bolt right up to either factory headers or aftermarket headers. They are also compatible with either factory or aftermarket exhausts. They also retain the factory converter "brace" (not shown in picture)

All of our converters come with new hardware including bolts, washers, and lock nuts.
