How To Make Stock N/a Louder

[Whoa Black Boaty]

I want to make my car louder without losing power. Any tips on what exhaust system will enhance power for my car? Any other way besides exhaust to increase sound and power

[Hadouken]

It'll be like 0.5 of a nanowat

[niZmO_Man]

Drill/punch holes in your muffler.

[Anfanee]

Remove the exhaust completely.

Cars get louder revving higher.

Therfore you should rev it higher.

Some interestingly useless replies.

Lets start at the top. Your thread states you want it louder, yet in your post you want more power. Well a well designed exhaust may gain a few "nanowatts" but free-flowing exhausts on NA cars do not yield much gains vs turbo cars. NA cars need backpressure to make power.

IF you want to make the car slightly louder remove the resonator from the exhaust and weld a straight pipe back in, this will retain the stock muffler/s and will help you get noise/not power

[Whoa Black Boaty]

Thank you^
Put I heard removing resonator loses back pressure and losing power.

Ben i do that already.

[niZmO_Man]

NA cars need backpressure to make power.

Fail.

Cover your nose and mouth then go for a run, that's backpressure.

The term you're after is "scavenging effect".

OP, your question doesn't make sense. Without touching the exhaust you won't get more noise and power... Unless you go ITBs with trumpets.

Get a set of well designed extractors

[Whoa Black Boaty]

Yeah extractors and exhaust system

Scavenging effect or more correctly exhaust gas velocity. Every engine want's as little back pressure as possible but NA's rely on scavenging more so the crossover of gas velocity vs lower back pressure is heavily in favor of gas velocity.

When i had my n/a r33, i got a cat back exhaust system for 100 bucks including canon, cat and hot dog reso. Car droned like a mofo, so i bought a adjustable 4 inch silencer from ebay, and had it partially opened. Worked like a charm, produced a nice tone with minimal to no loss of power. Im assuming the silencer created that "backpressure/increased velocity" that n/a's desperately desire. In fact, im pretty sure it became a little quicker, i started to pull (ever so slowly) on my mates n/a 34 after the exhaust "upgrade". Anyways im just talking from my past experience.

[Whoa Black Boaty]

bullshit 100, i thought i'd have to fork out about 1k for a decent exhaust.
I would want it to also make my car sound better not just louder.
Did you get pulled over a lot before you got the silencer?

[GH05T]

100 as stated will get you a shit exhaust which drones like a shit exhaust.
fitting a silencer (bottleneck) is not a good conter modification.

just get a decent exhaust proably a couple of hundred. and good headers maby another couple of hundred 2nd hand. maby 5-600 all up
after that just cam the thing

[Whoa Black Boaty]

can the thing? or cam as in camshaft?

[Anfanee]

Or don't bother and wait till you get a decent car.

[GH05T]

camshaft.
the only way to make an engine give more killawasps in basic terms is increase the fuel and air intake and get the waste out.

with either forced induction which in not your option here
make it rev harder

or increase the capacity

I don't understand why people say this. I'm not able to get my full license for over 3 years. Out of p plate legal cars i got one of the best cars in terms of power for my restrictions. May as well improve it and learn as much as i can before i go for a turbo car.

Camshaft makes the car rev at a higher rpm correct?

I've already got a k&n air filter. how do i increase air more than that? and not sure what mods will increase fuel flow.

increase capacity of power?

[Anfanee]

lol says like we don't understand.

The restrictions are nothing new. I too had to wait. I too got an N/A skyline.

The best thing i did to it was nothing. It was a car i liked the look of. Why waste cash on mods that will literally do nothing to improve the car? and just ask for more cop attention? Complete waste of cash.

Put said money that you are going to spend into a savings account. And come opens you will have a heap more to spend.
