Looking at first mod on '05 coupe...
Cold air intake.. K&N

What sound difference is there?
Both inside and outside?
I've heard some say it adds to interior noise. .
Thanks

 

It's nothin to worry about

 

I run a stillen CAI with the Z tube, you don't notice any sound difference until you get on it.

Then it sounds louder than the stock intake setup.

Can't speak to other CAI's

Another good mod for the $ is a grounding kit Sean sells them on the forum, user name is SxExCx. Smoother idle, crappy Bose stereo even sounds a little better. Recommend checking it out.

 

I personally love my Nismo CAI, sounds a whole ton lot better than stock. TDX2 is next for me ^_^

 

You'll love the sound from a new intake sounds awesome when hitting the gas peddle you can hear the wind sucking up...and krilla95 the TDx2 if worth every penny! Will never go back...after that add some Berk HFC it's HEAVEN lol

 

tdx2 + art pipes is my route hehe

 

Adds a slight whistle at certain RPM, nothing that's overwhelming.

 

The Bose system on the 05 isn't crappy its the actual head unit. If u spend the money to get a new jdm double din dash plate and a descent head unit it's a world of a difference trust me.

And I have a K&N 69 series typhoon cold air intake an it sounds alot better then the stock set up and if u ever get a kinetix intake manifold ull hear the cold air intake start to suck in air around 2-3000 rpm an it's even sexier good luck with ur mods

 

I've got a JWT POP charger and Z-tube, dosn't get any louder then stock till you give it over 50% throttle. It sounds great, deep and smooth.
