exhaust

First of all im new and im looking for a bit of advice. I have just bought a 1.2 Fiat Punto avtive sport 8v 04plate and im looking to fit an exaust. Firstly what is the diffrence from a full system and a back box? How much should I pay for each? and does anyone have any pics of exhaust of a similar model just to get an idea of sizes and looks etc.

Thanks

anyone?

heres a pic of mine and a video, the video was when i forst got it on but its not louder and growls more. It also sounds loads better in person.

full system is from the manifold straight through the under neath of the car... i.e manifold, center box an back box...

the full system is always better because you can have a bigger pipe fitted... bigger pipe means you can get air out quicker.. a major benifit if your planning on fittin a induction kit

pointless fittin induction kit if you cant get air out just as quick...

(back box is just back box... quick way on makin car sound and look good)
