Hey guys, I'm a new G owner. I found threads that were closed about how to make the stock sound deeper and louder. Looks like the Fast Intentions HFC were the answer, but I live in CA, so its illegal to have HFC's and not even sure if it would pass smog.

So is there another part I can mod to keep the stock sound and make it deeper? I was told headers with a intake would do?

 

The HR Y-pipe helps and gives a little giddyup

 

Coupe or Sedan?

My bad, I looked in your garage.......


There are several types out there, in fact there is a sticky on just exhausts with sound clips.

 

I was under the impression that changing the exhaust would totally change the note of the exhaust.

 

I put the HKS axle back on my sedan, it really didn't change the "tone" that much, a little deeper and louder though.

 

The best I've ever heard my exhaust prior to going FI was stock exhaust / cats with spacer and stillen hi-flow box / K+N cone filter. Same note, but the roar was much more prominent.

As long as we're just talking about the sound as opposed to performance...

 

Yeah, with my NISMO intake the roar is quite prominent over 4000 rpm.

 

That is true. Any aftermarket exhaust will change the unique tone of the G coupes exhaust note. Some for better, some for worse...It's all subjective.
As mentioned before the HR y-pipe is your best bet. It will amplify the oem sound slightly without changing it's unique tone.
Any HFCs will cause some rasp on the oem system, some more than others.
Vids are nice but they will not represent the true sound of any exhaust. best bet is to hear it in person.

To enhance the oem exhaust note even more air intakes and the motordyne spacer help. MREV2 for sure if u have 6mt.

 

Looks like my current plan is HR Y-Pipe and a Nismo Cold air intake.

This seems like a good deal?

Unless anyone knows a better deal.

 

Nismo sounds pretty close to stock but louder.

 

I did the hr y-pipe and it did seem like it got a lil deeper under wot..

 

i always thought it was nuts for people to change out the exhaust on their coupe only to have it sound like any other Honda with a muffler. that's freaking nuts

 

That's what I'm seeing to saywat?... Time like that in the shop is $ wasted.

 

^ lol when I hear exhaust clips of g35s with exhaust and people saying how cool it sounds I jus laugh and think "are u kidding me?". the Honda down the road sound jus like that too lol

 

I swear I can hear a G when they pull hard from a mile away. But that Honda sound I instantly tune out.

Recently people have been saying, "new exhaust, gained 15hp!" When really they tuned after getting the new exhaust and that's where the gains are from.

Anything that makes your car feel faster and that brings back the driving experience is golden though. Going from G tube to Z tube was a huge change for me haha. Now it's a fight for noise... Intake versus exhaust pitch.
