SOUND CLIP exhaust. IS this normal?

TPrelude-370z

Hey guys,

Took a vid of the exhaust sound with the hiss.

Is this pretty normal as far as how audible it is and the actual sound?

I am going to try multiple avenues to fix this, so any thoughts are welcome

Setups

-erz resonated test pipes - no hiss

--test pipes plus obx y pipe - loud terribly sounding hiss

---test pipes, y pipe, 3" transition y to mid pipe back at 2.5"

I have purchased a different y pipe with different design as the obx is know for creating a loud hiss.

I am also installing a g2 intake which will probably not make a difference in hissing sound.



To finish off the header back exhaust I will be adding a quality transverse muffler like many of the exhaust kits have to see how well everything sounds together.

I pieced the exhaust together this way for this very reason. I wanted to see and feel the change in power and exhaust tone from each part installed. If I put everything on together with an expensive cat back, I wouldn't know what was creating what gains and what sound. Plus it only cost me 300$ for a cat back exhaust minus the muffler.
