Cars today are made conservative for a reason...It opens them up to a bigger market, plus its less hassle for nissan down the road legally and warranty wise. If you want a louder exhaust get a new one. In my opinion the 370z doesn't have the sports car sound it should but thats why we have aftermarket parts...While i'll be the first person to bragg that my 370 is a nismo, i'll say that its also an exspensive brand name and that because its nismo doesnt mean it is the best...The exhaust is a prime example of that! My first mod and BY FAR the most important in my opinion. I couldn't be happier with it and everyone that hears it cant help but
