The Invidia stainless steel test pipe is a great additional to any exhaust system to maximize exhaust air flow. Though stock catalytic converters are there to filter out exhaust gases, these can be very restrictive and effect over performance. The Invidia test pipe eliminates this problem by connecting in-between your header and exhaust piping creating an even flow throughout the exhaust system. The Invidia test pipe is manufactured with stainless steel SUS304 and polished to a mirror finish. CNC machined flanges insure precise fit and durability. Oxygen sensor bungs are welded for use of stock oxygen sensor.
