2009–2018 Nissan 370Z 3.7L Test Pipe FAQs
Q1: Will these test pipes fit my 2009–2018 Nissan 370Z?

Q2: What section do these pipes replace?
A2: They replace the factory catalytic converter section. They are not exhaust headers, a Y-pipe or a turbo downpipe.
Q3: Do the pipes add horsepower?
A3: Flashark describes improved flow and an average gain of 10–20 horsepower, along with torque and throttle-response benefits. Actual results depend on the vehicle and complete exhaust setup.
Q4: Will the exhaust sound change?
A4: Flashark describes a louder, more aggressive sound than the stock catalytic converter section and a refined, drone-free character at cruising speed.
Q5: What material and construction are stated?
A5: These pipes are described as 16-gauge T-304 stainless steel with mirror polish, mandrel bends, TIG-welded joints and CNC-machined chrome-plated flanges.
