Thanks man right now currently I have the exhaust on my car not sure how good it is being that it's all motor.and just has a vented airbox. i removed the silencer, it looks hideous. Although when it's in no drone sound in cabin. i like without the silencer...it's more loud and fun what can I do about the drone in cabin ?

you can install a 3" silencer or whats also known as a "center resonator" on the midpipe.
My Zee's exhaust from Japan came with a built in center resonator. sounds quite-ish until you get on it and then it screams.
its 3" to the midpipe, where the resonator has a 3" input, and two 3" outputs that go to two 4" cans.
You will always get the drone without it unless you do extra restrictive bends to quite things down which is pointless.
Also since you are not turbo your exhaust noise will actually be louder than a turbo car which means your drone will be worse also.
Technically speaking a turbo acts as a type of silencer/muffler, so as an n/a with that large of an exhaust you have literally no restrictions except for the cat if you have it even.
