Worth upgrading nismo exhuast?
 

Curious for opinions on if getting an aftermarket exhaust is actually worth doing or even considered an upgrade. Right now I just have the Stock Nismo exhaust. I would really love a more aggressive sound and a little extra hp would be nice but wasn't sure if the aftermarket ones were that much better or not.

If you have the nismo exhaust I would say it's definitely not worth upgrading the catback. I would do some high flow cats though, they will give you more horsepower gains than any catback would over the nismo and they will give you that more aggressive sound you are looking for.

Simple answer is yes.

Buy a FI exhaust and HFCs and you'll never look back.

I would say yes, Nismo exhaust is not much better than the base Z exhaust. Aftermarket exhaust will make your Z sound more aggressive and definitely give you gains over the Nismo exhaust.

Fixed

:iagree:

Kinda illegal but absolutely for a track car.

Fast Intentions exhaust. Do it. Do it now!

Fast Intentions... Problem solved. :happydance:

Whats so great about the Fast Intentions exhaust? I heard the Motordyne E370 and it is by far the best Z sound I have ever heard! Period!

When comparing to the E370 cost is the biggest difference. Also, isn't the E370 obscenely loud? With FI you have multiple resonator options available.

The E370 comes with a middle muffler and two HKS style resonators out back. It is quiet when you are cruising and loud when you step on it! Here's a video:

ENJOY :tiphat:

Go hear one in person and you'll see. Also has top gains of exhausts on the market for half the price of others.

Way to flippin loud!
