As above anyone Know what the best exhaust for an st170 would be.

The standard one! Knock the cat out (or decat) for a nice rasp at WOT

If you must change it, the Magnex systems for the focus fit well, sound nice, and work well.

Decat sounds terrible on the ST170 and LOUD, keep the cat or fit a sports cat and a mongoose system which the blueflame is a copy of. Miltek is THE best but expensive.

been having a look at prices and they seem to be £300 upwards which isn't too bad.Not looking for anything too loud but just a nice burrble a tad louder than standard.

Standard with decat and remove resonator box off the air filter box

I disagree - sounds like an S2000 car when you're giving it stick! Press the peddle harder

Blueflame are pretty poor quality wise. Miltec is good but you pay for it lol.
