Is it possible to boost a Civic without having that annoying loud pipe on the back? Or just get a quite one?

Well the turbocharger acts as its own kind of muffler, so a turbocharged civic will not be as loud as a n/a one. However if this is too loud then l would just add one or two resonators. These will make the car a lot more quiet without taking away too much power from the car.

Yeah it is possible. It just depends on what type off pipes or exhaust system you get. Be different and please do not get any annoying pipes thinking it going to make your car go faster. l hate people who think just because you have a annoying pipe or its loud, they think its all fast and powerful now. That is so stupid! But be different and choose something that people do not normally get. Like l said before it all depends on what you choose to put on, but its possible dude!

Actually it is very possible. Technically with a turbo setup the car has a manifold made just for the turbo exhaust routing, u can put any catback system on it that u want as long as it doesn't' restrict the airflow needed for the turbo to function properly. So if u wanted u could probably run a stock muffler as long as it does not bog the motor down when the turbo kicks in.

If you restrict the flow of the turbo then it defeats the purpose of putting one on in the first place. A quite exhaust you would only find from companies such as Greddy, HKS, Tanabe etc. who guarantees the decibels ratings that there exhaust systems produce even for such vehicles that are under boost. And still produce power from your turbo kit over having to keep your stock exhaust system on to keep from being too loud. GOOD LUCK.
