my motordyne 5/16 spacer came in 2 days ago woooooo!!! ready to get it on!!! but anyways has anyone who has this heard a change of tone from the exhaust?

 

Didn't notice a different sound from my then OE exhaust, did notice the extra HP in the seat of my pants....

now thats watsup proven performance LMAO!!!

 

It opens the engine sound up quite a bit especially with a pioneer charger and ztube

 

i got an intake also so it should sound great together. it will really sound badahhh with the hks high power but too expensive

 

the motor/exhaust definately sounds a bit different after installing the plenum spacer

 

I didn't notice any change but that may be because I put Berks HFC and an HKS replica on the same time and now my ears bleed when I floor it lol.

 

installed it earlier today and def did not notice any change at all except the exhaust note

 

Did you also install the intake you mentioned? When our VQ motors were manufactured Nissan made an error in the plenum so the two front ports don't receive the same amount of air as the other four. The spacer corrects Nissan's error and you should have felt a better response when you drove your G. You need a Z-Tube along with your intake and MotorDynes exhaust system to appreciate what it will do for your G35. Tell all your family and friends that's what you want for Christmas.

You have roughly 240 whp stock. You're not going to notice an 5-10hp increase.

 

OP you need to reset your ECU. And^^ a lot of folks on here, including me, definitely noticed an increase in performance after installing a spacer, nomsayin?

 

I seem to recall that MotorDynes instructions for installing my 1/2" spacer mentioned removing the negative side of the battery during install. Since I ordered the whole copper gasket thing and cleaned everything before putting it back together it took me an hour, that's long enough for the ECU to reset....which it did. I noticed the increase the minute we left the neighborhood, didn't want to wake anyone up!

You must be very sensitive to notice a 3% power gain at best. But yea, op, reset the ecu and maybe you'll feel something on your butt dyno.

 

Don't know about anyone else but i drive an automatic and my car was pulling like "hell yeah" when i put the spacer on...i'd say way more than 3% and the sound was and still is amazing

 

I dunno I didnt feel anything, but noticed the throttier intake noise. I felt the most when I paired it with the MREV2.
