A test pipe is the section of piping in an exhaust where the catalytic converter is. Removing the catalytic converter creates much higher exhaust flow. We have seen potential on improving the stock design, by using mandrel bent 304 stainless steel for optimum flow and corrosion resistance. TIG-welded by hand for race proven strength and durability, eliminating any cracking during heat cycles.
CEL ELIMINATOR / O2 SENSOR SPACER
This oxygen sensor spacer is used to remedy the CEL (Check Engine Light) that occurs when an aftermarket catalytic converter is installed on a modern vehicle. The primary use of the spacer is to take your O2 sensor out of the exhaust stream so that your O2 sensor senses less oxygen in the exhaust pipe.
These are designed for 350z / G35's using the DE engine. These will not fit vehicles equipped with HR engines.
