Depends on how loud you want it and then whether you're going to decat the rest of the exhaust at a later date (ie. making it much louder).

Everyone will post their own exhaust, because it's all about personal preference.

as said above,

let us know what you want from an exhuast and we can advise better.

whats important to you?

cost, loud, quiet, suttle, so big you could live in it??

my car had a TSL firestorm on it but after a couple of months the constant drone on the motorway got on my **** so i put the prodrive exhuast on which is a lot quiter and looks a lot better IMO.

that's my one in the youtube vid and i'd recomend the genome to anyone, the best backbox i've ever had and there's been a few

quiet when pootling around, no drone at all and howls like a nutter when you're flooring it. perfect

I'm happy with my RCM system, gives a lovely growl/burble so you know you've got a bit under the hood, but not so loud you cant live with it, I use mine is a daily driver and regular motorway trips

Love the sound of the Greddy Ti-C or the Invidia G200. Or the HKS Hiper or the Afterburner, or the Blitz!! So many choices. Have alook on youtube as said before.
