two different nismo exhaust????? (nismo car ver and S-tune ver?)

I have the Nismo S-tune and its significantly different than the OEM Nismo exhaust.

OEM Nismo: 1.75" Primary pipes that stay true dual throughout the exhaust. They increase to about 2.25"-2.3" later on down the pipe run near the mufflers. There is a H-configuration crossover near the engine. Flows better than the OEM 370z exhaust but is not as sharp or fancy in build construction as the S-tune. About a 5-6 hp gain max for swapping this in place of the OEM exhaust.

Nismo S-Tune: 2.4" Primary pipes, joining into a single 2.5" y-pipe, then splitting back to two 2" pipes, through two resonators which stay 2" inside then back up to 2.4" out the back and through the muffler. About a 3-5 hp gain max for swapping this in place of the OEM exhaust. It's also VERY quiet.


Personally, I got the Nismo S-tune exhaust and made some modifications. I replaced the "Y-section" and resonators with a 2.5" Stainless X-Pipe and Vibrant 2.5" Stainless 18" Resonators. Basically, the first half of the exhaust is a Berk X-pipe and it connects to the S-tune muffler. The whole thing is now 2.4-2.5" through and you can really tell the difference in power and response vs the off-the-shelf S-tune. I added ERZ high flow cats and called it a day. It's a whole new animal now and sounds awesome. Will be posting sound clips shortly. Not the cheapest way to make power but definately very unique sounding. Fast Intentions and or Berk is cheaper but lots of people have those.
