Hey there everyone, first poster here!

I've recently bought a crossfire! 55 plate, and I love it! I have had my alloys refurbished to get them back shining! They look great! Now I'm after advise on what to do for a more thoatier sound and more hp and faster top speed! I read bout getting it remapped? And an induction kit? I'm not much of a car expert lol, any advise will be greatly appreicated!
