Didn't know the ST170 came as standard with a sports cat, saved me a few hundred quid there, as I was looking at a sports cat next.
Not bad then.
Keep your std manifold as ebay cheaps tend to crack, you wont really get any better than the std manifold.
Yeah sports as std, iirc decat on these causes a loss in bhp and gain in torque or the otherway round lol, decat prices have gone up thay used to be £60 when I had a focus lol.
