How to make the exhaust sounds like those hks exhaust with deep bass rather than the high pitch sounds?thanks bros !

Bigger volume

Sorry i don't understand.

Impossible

thanks if cant make it sounds deeper..how about making it more quiet as i dont wish to disturb other people knowing that i might as well get a ep car but i like still perfer the smell and smoke !

....you will need a new cat - back system

High pitch = higher rpm = lean.
HKS exhaust tone means the engine is very rich

Hai so I guess I can't do anything to the pipe already.I searched online but no result..

if you are handy, you could try to make a custom exhaust. resonators ect arent that high tech and im sure you could fab somthing. your engines performance would probably go out the window though as the pipe is a big part of the performance.

very simple.... put a RC system in your 1/1 car with HKS exhaust and you are done. LOL Just joking.... As RC engines rev much higher than 1/1 it is really hard to get a low pitch tone..... Anything maybe closer are the 1/5 as they only rev to under 20,000 rpm. So the note is much lower compare to .12 or .21 engines.

All you need is a miniature turbocharged four stroke engine.......
Or maybe try a piece of straight thru pipe as it can be difficult to replicate the 'wet fart' sound of a HKS exhaust system.....

Adding a standard noise silencer can already lower the pitch quite a bit.

Use quiter pipe = change to smaller diameter stinger ( exhaust tip ), I think 5.2mm diameter tip. Expect longer run time and slightly less power.

Use carburator's air box.

Thank u guys I will search all possible way that u guys mentioned..
