Default I need help

in my country it is illegal to have loud exhaust sound for a street car. and i am planning to add headers X-Pipe and a cat-back.
is there any way that I can get the performance of headers, X-Pipe and cat-back without having a loud sound?

is there any quiet cat-back system? or maby another solution?

Why not just keep the stock exhaust behind the headers if performance is the objective? Cat-back won't make any power anyhow.

True only in the dreams of the manufacturers and vendors who sell them. Maybe 2-3 additional horsepower with something like Bullets, but no more.

I have headers and stock exhaust and the sound is not that dramatic. You should be good with that set up.

If you need it absolutely quite and you still want an exhaust you could try the corsa touring...but they do not work with headers because of the resonators.

I would for sure get headers and skip the exhaust if i was in your situation...cat back wont give you much hp

The corsa sports are not loud unless you are at WOT. I have LG's xpipe high flow cats and corsa sports and it sounds just a little louder than stock at idle

Try and get a sound bite of Corsa Touring. Quiet at idle and cruise, wicked loud at WOT.

I have heard the sound of corsa touring with headers and I think the best way for me is to have headers and X-Pipe and leave the stock cat-back

I don't get it. Headers can produce how much HP with stock pipes. What would be the reason for this set up? I though cat back would be first option w/o being to radical and if u want to be that then headers. Any thoughts guys?

Headers will give you the same power gain with or without an aftermarket catback exhaust. The OEM exhaust is very efficient, it's just too quiet for those who like a deeper/louder exhaust sound.
