Does a test pipe make a difference?
more sound than anything. The increase in diameter of going to a 2.5" high flow cat from stock would give you some gains, but a test pipe won't be much more over that. It's mostly a sound thing. via
What do ISR test pipes do?
Utilizing a small resonator, the ISR Performance resonated test pipes will help cut some of the rasp of the exhaust note of your modified VQ while still providing much better exhaust gas flow than the OEM catalytic converter. via
Does a test pipe need a tune?
Hey guys i plan to get some MS test pipes . Will i need a tune to run them? No. A tune is recommended but not needed. via
Does test pipe make car louder?

What is a car test pipe?
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. For turbocharged cars this results in less back pressure and better flow for the turbine. via
Does 370Z exhaust fit G37?
The G37 exhausts will not fit the 370Z due to the different mid-pipe. The headers, cats, and y-pipe are interchangable. via
Can G37 test pipes fit a G35?
manifolds are different so the G35 test pipes wont bolt up directly. unless you swap manifolds is the only way it will work. will not fit. G37 and 370z are the same. via
Are test pipes worth it 350z?
Overall, ISR Performance's test pipes will give your 350z a nicer, deeper tone than you'd have without them. At such an affordable price, these are definitely worth a look. via
