Want to mod my Nismo but soooo confused
 

I've read so many different opinions on mods that I'm left confused. I've got a 2013 NISMO and would like a little louder sound with a little more power.

I'm thinking of adding:
STILLEN 409 Stainless Steel Headers - Ceramic Coated -
STILLEN Stainless Steel Exhaust Systems - Dual Wall Tips -

My confusion lies in the best bang for the buck and I'm also worried about adding either one mod or a combination that effects power negatively somewhere along the power-band.

For instance, I read somewhere this morning in a thread that said changing the headers is bad place to start because you don't get much of a power gain.

I've also read so many conflicting opinions on the stock cat back that I don't know if changing it is even a good idea.

Or should I just go with the Visconti tuning for $1k? This option intrigues me.

Ugh!

I would skip the headers and save your money for either a tune or another mod you want...Stillen headers are low on the bang for buck ratio. Getting a proper tune will help across the entire rev range.

Get Berk or FI HFC with an intake and tune. Or go FI all the way.

You're throwing your money away if you go with shorty headers with the exception of the Z1 headers. The only headers that are worth a damn on a Z are long tube headers (except the previously mentioned Z1 headers). Just know that if you have to worry about inspections you're going to have issues by having the long tube headers.

If you do any type of header. The left side WILL take you 5 plus hours to do it. The right side only 1 hour. Been there and did it. Best bang per buck. G3's, CBE, and a tune to smooth out the power band and A/F. And a oil cooler.

I agree with all above.

Best bang for the buck IMHO would be: (in order)

1. HFC (Berks are nice) By far best bang for the buck if done with tune!!!
2. TUNE (most guys use dyno UPREV at local speed shop)
3. drop in replacement filters (K/N) or long tubes (don't bother with short tubes like JWT's because heat soak will steal much of the benefit...I know I have them)
4. CBE. expensive with slight gains...really just makes it sound better which is awesome.

Forgot about the HFC's. :(

best bang for the buck is to leave it stock. i know crappy answer but i would add an exhaust and drop in some K&N filters and call it a day. maybe a tune down the road.

if you want bang, then FI!!!!! but you will pay.......

I think I would
AAM axle backs (Louder sound)
UpRev Tune
K&N Filters
If you race your car at all then an oil cooler.

Twin turbos

lol...

I think he only has 1k to spend.

not enough to really do a lot to the car. HFC and Exhaust with a tune.. but a tune alone will run you $500. I say, save your money until you can get it all done. If you get a tune first, then upgrade, you will need a tune again.

GTM is releasing a 1.5K TT kit using ebay turbo whistlers supposed to make 1000hp

Anybody can make 1,000 HP...


...once.


The trick is doing it over and over again. :tup:

but those whistlers are on back order man!!!! and the supplier is swamped!!!!

Stillen G3 Long Tube CAI or similar will make your car louder at high RPM and you'll get a very small bump in performance. If you buy a set used you can get away with paying between $300-$350. Installation isn't too bad either, plenty of DIY's here on how to do it

Actually, right now about $2500
 

I'm looking to spend no more than $2500 right now. The $1,000 mentioned in my post was referring to getting a Visconti tune.

First, very nice sound. Love it! Question, though, what is the difference between axel backs and cat backs. Sound? Performance? Is there a specific reason for going with one over the other?

Thanks.

When your talking basic bolt on's an engine is a basic air pump. The reason you shouldn't start with headers is because generally the catback on cars is restrictive. So if you replace headers your still going to be bottle necked by the catback. Its like a hose, regardless how big free flowing the end is if the front is kinked your only going to flow so much. Since you have a nismo from a power standpoint replacing the catback is a waste of money (unless you want a different tone). So for you it might make sense to start with headers, high flow cats, or intake.

IMHO the OP is probably best off getting this: Z1 400 HP Package, Stillen G3's, and a tune. Then save some more money and get a Fast Intentions CBE.

For what it's worth, F.I.'s 2.5" TDX is probably the most efficient bolt on you will get. Do drop ins filters and hard pipes (those may be custom), then you can see if you want to do more than tune. Maybe HFCs or TPs, but I wouldn't know. I went from 2.5" TDX and high flowing filters to twin turbo and 3" TT-TDX (well more than just that, but you get the idea).

Stillen intake and either litespeed titanium exhaust or fast intentions are the top choices for bang for the buck
