im getting my nismo exhaust tomorrow and thinking about getting some injen test pipes how much louder will that it? Anyone have any expereince with this combo?thanks.

 

i had the nismo setup and than i added high flow cats and it was much louder. test pipes will be even louder. so the answer to you question is yes definitely. try the search button first next time, you will catch a lot of heat if you dont. great sounding setup btw

 

Injen makes test pipes for the 350Z? Photos? Link?

The exhaust will be more noisy with test pipes yes. No one makes measurements, but I would say a decibel or two louder.

 

Be advised that test pipes/high flow cats and California do not mix well.

Of course you can't judge how loud that is but its pretty loud hehe. Its not bad cruising though which is what I like. At WOT its pretty mean.

 

I think your question has been answered...

1. yes people have nismo exhaust with test pipes
2. it is quite a bit louder than without test pipes
