Fast Intentions on NISMO
 

Hey guys,

Just installed F.I. on my NISMO. I have a question here: Does your cabin vibrates when you are accelerating?

I have 12''+ Non-res HFC. The drone from below 3.5k rpm is killing the car. The whole cabin vibrates and I can hear the shaking, especially the rear wing section was really singing with the exhaust. I can live with the hiss and the loudness, but the shaking+metal clunks makes me feel a little uncomfortable.

Don't get me wrong, this is a very good sound system. I feel like I'm sitting on a night club's stereo.:tup: My rear resonates on the seat with my car's rear.
Any thoughts? Thanks guys.

update: not vibration, buzzing.

Earthquake.

Sounds like my honduh civic back in highschool with its muffler removed. Fun times! :tup:

Some dynamat in the hatch will go a long way. Also, keep in mind that the exhaust will tame down a little after the first few 100 miles. Not sure how much you have driven it at this point.

already did 150 or so

you can't be in illinois and have that frequent earthquakes...:tup:

the point is: I have mufflers:confused:

Exactly ;)

I have a little trunk rattle but not much at all.. it changes with the weather too. more rattle in the cold weather.

If you're hearing clunking and metal-on-metal noises, you need to crawl up under there and see where it's rubbing on either the chassis braces or the evap shield.

I have the same setup as you and got the rattle in the back as well. I pulled the rear hatch plastic and put some one sided foam weather stripping around the perimeter and where the plastic has the step about half way up. The foam I used was 1/4 inch stuff I got from lowes and that did the trick. Once you get 750 to 1000 miles you will notice it mellow a little.

Thanks. I've been trying to figure out how to describe the noise. I think the word is "Buzz". The rear really buzzes starts 1.8k rpm up to 3-3.5k.

I don't know why this word didn't come across my mind sooner.:owned:

Yup, mine does buzz a little, but if I don't wont to hear it, I just mash the gas....it goes away!

LOL Nismo on raw meat and roids. I'll bet that sumbitch buzzes just shy of lightspeed.:inoutroflpuke:
