How Good is the OEM Nismo Exhaust?
The Nismo 370Z comes stock with True dual exhaust already, that makes me wonder if switching to another dual aftermarket exhaust is worth it. Should I keep the Nismo configuration and change the Axleback only or just switch out the entire system?
How good is the Nismo-tuned exhaust that comes stock on the Nismo version? Anyone know the piping diameter of the exhaust?
Will I see any gains or is it worth to change the system to an aftermarket dual exhaust?
